A Practical Model For Advanced Nonlinear Analysis Of Earthquake Effects In Clay Slopes, Mahdi Taiebat, Amir M. Kaynia
A Practical Model For Advanced Nonlinear Analysis Of Earthquake Effects In Clay Slopes, Mahdi Taiebat, Amir M. Kaynia
International Conferences on Recent Advances in Geotechnical Earthquake Engineering and Soil Dynamics
Presented in this paper is an effort in providing an advanced yet practical tool with a reasonable level of complexity for modeling of clays in realistic geotechnical engineering problems. SANICLAY model is a Simple ANIsotropic CLAY plasticity model that has been developed by Dafalias et al. (2006). The SANICLAY model provides successful simulation of both undrained and drained rateindependent behavior of normally consolidated clays, and to a satisfactory degree of accuracy of overconsolidated clays. An associated flow rule extension of the SANICLAY model has been employed in the present study, trading simplicity for some accuracy in simulations. The model requires …

An Evaluation Of Ground Vibrations Induced By Heavy Free-Falling Structural Elements, Kwangkyun Kim, Mark J. Carlson, Duhee Park
International Conferences on Recent Advances in Geotechnical Earthquake Engineering and Soil Dynamics
Ground vibrations generated during a large structural demolition event can be potentially damaging to nearby structures or sensitive equipment. In this paper, an approach for the prediction of the ground vibration induced by a large free-falling heavy weight is proposed based on both measured and collected data. A series of field ground vibration measurements were performed relative to the dynamic motions induced by free-falling heavy structural elements during demolition of a generating plant in the upper Midwest, USA. Using this information and the collected data, correlations between the measured PPV and normalized distance from the impact source with various ground …

Assessment Of Liquefaction/Cyclic Failure Potential Of Alluvial Deposits On The Eastern Coast Of Cyprus, Huriye Bilsel, Goknur Erhan, Turan Durgunoglu
International Conferences on Recent Advances in Geotechnical Earthquake Engineering and Soil Dynamics
The main objective of this paper is to evaluate liquefaction potential and cyclic failure of subsoils of Tuzla area located on the eastern coast of Cyprus. The in-situ tests of cone penetration test (CPT) and standard penetration test (SPT) were used for site specific evaluation of liquefaction potential. Index properties and undrained shear strength (su) were used to assess cyclic failure potential of fine-grained soils. Liquefaction potential index (LPI) was evaluated based on the calculated factor of safeties for each CPT location. Sensitivity of soils was indirectly estimated from liquidity index (LI). The samples tested displayed high sensitivity …
Comparison Of Measured And Estimated Shear Wave Velocities In A Seismically Active Area (Erbaa, Turkey), Muge Akin, Steven L. Kramer, Tamer Topal
Comparison Of Measured And Estimated Shear Wave Velocities In A Seismically Active Area (Erbaa, Turkey), Muge Akin, Steven L. Kramer, Tamer Topal
International Conferences on Recent Advances in Geotechnical Earthquake Engineering and Soil Dynamics
Shear wave velocity (Vs) is an important parameter for the design of geotechnical works in seismically active areas. The Vs value commonly reflects geological information and engineering properties such as stiffness and density. It is also an important parameter of soil for design and site response purposes. As a part of a microzonation study, field tests performed in Erbaa, Turkey were evaluated to obtain shear wave velocity profiles. The study area, Erbaa, is located on the eastern segment of seismically active North Anatolian Fault Zone (NAFZ) where a catastrophic earthquake occurred in 1942. In addition, several earthquakes …

Cyclic Compression Of Compacted Clayey Sand At Small Cyclic Strains, Mladen Vucetic, Macan Doroudian, David W. Sykora
International Conferences on Recent Advances in Geotechnical Earthquake Engineering and Soil Dynamics
Ten drained cyclic strain-controlled direct simple shear tests were conducted on compacted low-plasticity clayey sand to measure its cyclic compression properties. The soil had 37 % fines, liquid limit of 28% and plasticity index 14. The relative compaction of specimens prior to consolidation and cyclic shearing was between 80 and 90 %. Cyclic compression is expressed as the accumulation of vertical strain with the number of cycles, N. Vertical strain recorded at the end of every cycle, ενc, increased with the cyclic shear strain amplitude, γc, and N. Such behavior is typical and has been obtained …
Cyclic Response Of Reconstituted Low Plasticity Silt, Selman Sağlam, B. Sadık Bakır
Cyclic Response Of Reconstituted Low Plasticity Silt, Selman Sağlam, B. Sadık Bakır
International Conferences on Recent Advances in Geotechnical Earthquake Engineering and Soil Dynamics
Foundation failures observed over saturated silt-clay mixtures during past earthquakes clearly indicate the need for a profound understanding of the behavior of such soils under seismic loading. Although the mechanisms dominating the response of fine grained soils under seismic loading are known to be different from those of sandy soils, the behavior of low plasticity silt and clay is still under discussion. An experimental research program, still in progress, has been undertaken to investigate the cyclic behavior of low plasticity fine grained soils for developing useful guidelines for the assessment of seismic response. Samples of low plasticity silt, initially consolidated …
Determination Of Small Strain Modulus And Degradation For In-Situ Weathered Rock And Old Alluvium Deposits, Erin Leung, Jack Pappin, Raymond Koo
Determination Of Small Strain Modulus And Degradation For In-Situ Weathered Rock And Old Alluvium Deposits, Erin Leung, Jack Pappin, Raymond Koo
International Conferences on Recent Advances in Geotechnical Earthquake Engineering and Soil Dynamics
The small strain shear modulus (G0) and the degradation of shear modulus (G/G0) with increasing magnitude of shear strain are important soil properties required for the evaluation of site response due to earthquake effects. While these properties are well established for geologically recent alluvial sand and clay materials, published data on the properties of materials derived from in-situ rock weathering and ancient alluvial deposits are limited. This paper presents the results of laboratory testing on completely decomposed granite and tuff in Hong Kong, and weathered Jurong Siltstone and Old Alluvium in Singapore. The small strain shear …
Constitutive Models Predicting The Response Of Clays Along Slip Surfaces, Constantine A. Stamatopoulos
Constitutive Models Predicting The Response Of Clays Along Slip Surfaces, Constantine A. Stamatopoulos
International Conferences on Recent Advances in Geotechnical Earthquake Engineering and Soil Dynamics
The paper proposes and validates a constitutive model simulating the change of resistance along clay slip surfaces under both undrained and drained conditions. The proposed model is based on (a) the critical state theory and (b) the assumption that the critical state changes once failure is reached, in terms of the further shear displacement. Under undrained conditions, the proposed model simulates the excess pore pressure generation and subsequently the continuous change of clay resistance along the slip surface from its initial value to the peak strength and then at large displacement the residual value measured in constant-volume ring shear tests. …

Dynamic Properties Of Rubber Specimens, B. N. Madhusudhan, Jyant Kumar
Dynamic Properties Of Rubber Specimens, B. N. Madhusudhan, Jyant Kumar
International Conferences on Recent Advances in Geotechnical Earthquake Engineering and Soil Dynamics
Resonant column and bender element tests were conducted on rubber specimens to study their dynamic properties, namely, shear modulus (G), damping ratio (D) and Poisson’s ratio (ν). It was found that similar to soil specimens, with an increase in strain level, the shear modulus of rubber decreases continuously whereas the damping ratio increases. The tests were also carried out to find the effect of confining pressures on the rubber specimens. It was observed that for the rubber with the lesser hardness, there was a slight increase in the shear modulus and a decrease in the damping ratio values as the …
Dynamic Properties Of Sand In Constant-Volume And Constant-Load Tests, F. Jafarzadeh, H. Sadeghi
Dynamic Properties Of Sand In Constant-Volume And Constant-Load Tests, F. Jafarzadeh, H. Sadeghi
International Conferences on Recent Advances in Geotechnical Earthquake Engineering and Soil Dynamics
Constant-volume and constant-load tests were performed on Babolsar and Toyoura sands by using a modified SGI cyclic simple shear device which provides the capability of back pressure saturation. All tests were shear strain controlled and conducted under different values of relative density, vertical effective stress and shear strain amplitude. Results revealed that Dr, σ′v and γ affect shear modulus and damping ratio under both constant-volume and constant-load conditions in similar ways except the shear strain amplitude which has no important influence on damping of constant-volume tests. The effects of Dr, σ′v, γ and …

This paper describes and compares the results of in situ and laboratory investigations performed on two Italian sites: St. Giuliano di Puglia (CB) located in the Molise region and Tito Scalo (PZ) located in the Basilicata Region. The tests were carried out to determine the variation of shear wave velocity with depth and strain level by Seismic Dilatometer Marchetti Test (SDMT), Cone Penetration Test (CPT), Noise Analysis Surface Waves (NASW), Down-Hole (DH) Test and Resonant Column Tests (RCT). Some considerations on shear modulus degradation evaluation by SDMT are proposed. The available data also enabled one to compare the shear modulus …
Effect Of Degree Of Weathering On Dynamic Properties Of Weathered Granite Soils, Woong Jong Park
Effect Of Degree Of Weathering On Dynamic Properties Of Weathered Granite Soils, Woong Jong Park
International Conferences on Recent Advances in Geotechnical Earthquake Engineering and Soil Dynamics
The strength-deformation characteristics of weathered granite soils are determined by the characteristic of bedrock before the weathering and weathering environment. Generally, the degree of weathering is changes with depth and affects the dynamic properties of soil. But there are very few studies of the effect of degree of weathering on dynamic properties of soils in Korea. In this study, dynamic tests were performed with resonant column after preparing the specimens which were remolded with disturbed soils, and the effect of degree of weathering on dynamic properties, such as shear modulus, damping ratio is considered. In addition, the relationships among shear …

A geotechnical experimentation site is being developed near Georgetown, South Carolina, to study the effect of soil age on liquefaction resistance. The site is located in an area called Hobcaw Barony on a 200,000-year-old beach to barrier-island sand deposit. Initial investigations conducted at the site include seismic cone penetration tests with pore pressure measurements, standard penetration tests with energy measurements, seismic crosshole tests, dilatometer testing, and fixed-piston sampling. Shear-wave velocities calculated from seismic cone test results are based on the true-interval method. The near-surface sand deposit extends from the ground surface to a depth of 8.5 m. The groundwater table …
Evaluation Of Liquefaction Potential Of Soil By Down Borehole Method, Sumit Ghose, Ambarish Ghosh
Evaluation Of Liquefaction Potential Of Soil By Down Borehole Method, Sumit Ghose, Ambarish Ghosh
International Conferences on Recent Advances in Geotechnical Earthquake Engineering and Soil Dynamics
The procedure used in this research work for evaluation of liquefaction potential due to earthquake is by correlating the cyclic stress ratio(CSR) and the cyclic resistance ratio(CRR) obtained from standard penetration test and shear wave velocity. Shear wave velocity in the different layers of soils have been determined by the use of down borehole instrument. P- and S-wave velocity data of nearsurface soils (upper 21 m) are analyzed and correlated to depth and sedimentological properties. The results show that the S-wave velocity is much more sensitive to changes in lithology and mechanical properties than the P-wave velocity, which is characterized …
Failure Of Saturated Sand In Non-Symmetrical Cyclic Loading, J. Yang, H. Y. Sze
Failure Of Saturated Sand In Non-Symmetrical Cyclic Loading, J. Yang, H. Y. Sze
International Conferences on Recent Advances in Geotechnical Earthquake Engineering and Soil Dynamics
Extensive experimental studies have been focused on the cyclic behavior of saturated sand under free-field level ground conditions when subjected to earthquake loading. In many practical applications involving earth dams, slopes and buildings, however, soil elements are always subjected to initial static driving shear stresses on the horizontal planes. The impact of initial shear stresses on cyclic behavior and strength of sand is not yet fully understood. The focus of the present study is placed on the initial shear impact on the failure mechanisms of saturated sand varying from loose to dense state. Three distinctly different cyclic failure patterns have …

International Conferences on Recent Advances in Geotechnical Earthquake Engineering and Soil Dynamics
Aquifer and hydro system compaction is a worldwide phenomenon, where there is a sudden sinking or gradual downward settling of the earth's surface with little or no horizontal motion. This phenomenon is noticed to take place in many countries, among which is Iran. Water well casing and installations in areas such as Hamedan , Kerman, Meshhed, Tehran and others seem to rise into the air, or some times to produce fissures in the sediments and/or showing sinkhole in carbonated rocks. Soil compaction and / or land subsidence could cause damages to surface and subsurface urban installations. UNISCO was interesting in …
