Settlements Of Three Buildings Founded On Stratified Soils, Enrico Conte, Giovanni Dente, Antonello Troncone Apr 2004

Settlements Of Three Buildings Founded On Stratified Soils, Enrico Conte, Giovanni Dente, Antonello Troncone

International Conference on Case Histories in Geotechnical Engineering

This paper describes the movements experienced by three residential buildings located in Avellino (South Italy). A common feature of the buildings is the unsymmetrical superstructure that, for lack of construction joints, makes the resultant of the vertical loads on foundation to be highly eccentric. At the end of December 1983, when most of the dead loads had been applied, the buildings exhibited conspicuous settlements, so construction was stopped and the vertical displacement of several points of the foundation was measured during a period of almost one year. The subsoil was investigated by boreholes, CPT and conventional laboratory tests; it consists …

Landslide Monitoring And Remediation – A Case History, Fan Xi, William Broderick, Paul Rizzo, Jeffery Bair Apr 2004

Landslide Monitoring And Remediation – A Case History, Fan Xi, William Broderick, Paul Rizzo, Jeffery Bair

International Conference on Case Histories in Geotechnical Engineering

An ancient landslide is situated in the vicinity of one of the two reservoirs of a pumped storage power project. Ground movements of the landslide accelerated following the construction of the reservoirs about thirty years ago. Though at a relatively low rate of movement, the active landslide jeopardizes the serviceability of transmission lines and roads traveling through the landslide area. The landslide also poses a potential threat to the adjacent reservoir. Based on long-term monitoring and thorough engineering investigations, remedial measures were developed and implemented in an effort to stabilize the active landslide. Different facets of the remediation construction were …

Shear Strength Of Franciscan Complex Melange As Calculated From Back-Analysis Of A Landslide, Carl Kim, Charles Smell, Edmund Medley Apr 2004

Shear Strength Of Franciscan Complex Melange As Calculated From Back-Analysis Of A Landslide, Carl Kim, Charles Smell, Edmund Medley

International Conference on Case Histories in Geotechnical Engineering

A methodology was developed to evaluate causation of a complex landslide that occurred in Franciscan Complex melange during the winter of 1996-1997 in San Mateo County, California. Conventional back-analysis methods to evaluate shear strength parameters were insufficient because the basal failure plane traversed three materials (fill, block-poor melange, and block-rich melange). Instead, using field observations of landslide kinematics, review of available subsurface data, and previous experience with Franciscan melange, a methodology was developed that incorporates the location of critical failure surfaces generated by random search routines in PCSTABL5M as an additional constraint. The methodology was employed to evaluate the relative …

Expreriment Of Seismic Failure Of A Long Embankment, Seiji Kano, Yasushi Sasaki, Yoshiya Hata Apr 2004

Expreriment Of Seismic Failure Of A Long Embankment, Seiji Kano, Yasushi Sasaki, Yoshiya Hata

International Conference on Case Histories in Geotechnical Engineering

Seismic damage to long structures such as river dikes, fill-type dams, and road embankments has been sometimes found to take place at locally limited spot. Local failures of a long embankment during an earthquake are mainly due to heterogeneous ground condition. However there are some cases that local failures were took place even though the ground condition was homogeneous. One of the factors causing local failures under such conditions may be the three dimensional response of the embankment. In this paper, the typical failure of the Kushiro River dike is reported. This paper aims to clarify the influence of three-dimensional …

Shear Strength Characteristics Of Heavily Glaciated Soils Of Chugach Range, Sukhmander Singh Apr 2004

Shear Strength Characteristics Of Heavily Glaciated Soils Of Chugach Range, Sukhmander Singh

International Conference on Case Histories in Geotechnical Engineering

As a part of the evaluation of the stability of cut slope of 55% grade, during the construction of Trans-Alaska pipeline, it was realized that the estimation of the strength characteristics of the glaciated till forming the slopes is vital to the analysis and the design of these slopes. Accordingly undisturbed samples were hand carved from block samples and were tested fro shear strength. An usually high effective angles of friction, 45° - 48° (Singh, 1976) were obtained. However, these high values of friction were found to be inconsistent with the maximum angle which the cut slopes can withstand. The …

Shear Wave Velocity And Its Effect On Seismic Design Forces And Liquefaction Assessment, Thomas G. Thomann, Khaled Chowdhury Apr 2004

Shear Wave Velocity And Its Effect On Seismic Design Forces And Liquefaction Assessment, Thomas G. Thomann, Khaled Chowdhury

International Conference on Case Histories in Geotechnical Engineering

The shear wave velocity of soil and rock is one of the key components in establishing the design esponse spectra, and therefore the seismic design forces, for a building, bridge, or other structure. The shear wave velocity can be measured from in-situ field tests, such as cross-hole or downhole testing. The shear wave velocity can also be estimated based on empirical correlations with other field collected information. This paper presents case histories from 8 bridge projects performed in the northeastern United States where in-situ measurements of shear wave velocities were performed for site-specific ground motion studies. A comparison of these …

Back Analysis Of The Liquefaction Failure At King Harbor Redondo Beach, California, Constantine A. Stamatopoulos, Stavros G. Aneroussis Apr 2004

Back Analysis Of The Liquefaction Failure At King Harbor Redondo Beach, California, Constantine A. Stamatopoulos, Stavros G. Aneroussis

International Conference on Case Histories in Geotechnical Engineering

During recent earthquakes small dams and embankments suffered large settlements as a result of earthquake-induced liquefaction. One such case is the mole embankment that settled about 1.2m and was displaced horizontally by about 2m at King Harbor Redondo Beach, California as a result of the Northridge earthquake of 1994 (Kerwin and Stone, 1997). The conventional sliding-block model has shortcomings in back-estimating the critical acceleration and corresponding strength of such earthquake-induced slides when seismic displacement is large. The reason is that the change on geometry of the sliding mass, that greatly affects the seismic displacement, is not modeled. Stamatopoulos et al …

Seismic Response Analysis Of Historical Towns Rising On Rock Slabs Overlying A Clayey Substratum, G. Lanzo, L. Olivares, F. Silvestri, P. Tommasi Apr 2004

Seismic Response Analysis Of Historical Towns Rising On Rock Slabs Overlying A Clayey Substratum, G. Lanzo, L. Olivares, F. Silvestri, P. Tommasi

International Conference on Case Histories in Geotechnical Engineering

Two case histories are presented which refer to the historical towns of Orvieto and Bisaccia, both located on top of rock buttes overlying a more deformable clayey substratum. The comparison of the two case histories indicates that apparently similar geological conditions do not lead to the same type of seismic response. In fact, the specific physical and dynamic properties of the substratum and the overlying slab can determine different seismic behaviour at the hill top and at the rock-clay interface. In particular, at Bisaccia a deamplification of the seismic motion at the hill top was predicted, as well as the …

Shaking Table Tests On Effiency Of New Type Of Drains, Vlatko Sesov, Ikuo Towhata, Naoyuki Harada

International Conference on Case Histories in Geotechnical Engineering

One method to mitigate liquefaction-induced hazard is the use of a system of vertical drains to dissipate the excess pore water pressure generated by earthquake loading. Performance assessments for these systems require the estimation of vertical drain spacing such that a maximum threshold level of excess pore pressure ratio is not exceeded. The objective of this research is to study efficiency of installing vertical drains on generation and dissipation of pore water pressure. For this purpose series of shaking table tests were performed using a laminar box, in Geotechnical Laboratory on Tokyo University. The ground model consists of two layers …

Measurements And Numerical Prediction Of High Speed Train Vibrations, Janusz Kogut, Geert Degrande, Geert Lombaert, Lincy Pyl, Wim Haegeman, Lutz Karl

International Conference on Case Histories in Geotechnical Engineering

This paper discusses the experimental validation of a numerical prediction model for train induced vibrations. The model fully accounts for the dynamic interaction between the train, the track and the soil. The track is modelled as a longitudinally invariant system, where two beams represent the rails, while a plate with a rigid cross section represents the subgrade. The track is located at the surface of a horizontally layered elastic halfspace. The translational invariance of the problem geometry enables a solution of the equations of motion in the frequency–wavenumber domain. The model is validated by means of vibration measurements that have …

A Case Of Soil Sliding In The Pathology Of Retaining Structure, J. Matos E Silva Apr 2004

A Case Of Soil Sliding In The Pathology Of Retaining Structure, J. Matos E Silva

International Conference on Case Histories in Geotechnical Engineering

Sesimbra is a village located on the Portuguese West coastline 70 Km South of Lisbon. It is a site of high cliffs, overlooking the sea, mainly formed by clays. The rainwater that penetrates the soil through permeable layers originates the clays sliding. Recent construction site in the area started with the execution of a retaining wall with counterforts. Some time later after a long rainy period the soil sliding created a high earth pressure on the retaining wall that originated the separation between the wall and its counterforts. The paper describes the pathology and its repair.

Deep Supported Excavation In Difficult Ground Conditions In The City Of Patras, Greece — Measured Vs. Predicted Behavior, D. P. Zekkos, A. G. Athanasopoulos, G. A. Athanasopoulos

International Conference on Case Histories in Geotechnical Engineering

The technical characteristics of a deep supported excavation project using anchored diaphragm walls and the measured (by inclinometers) behavior of the soil retaining system are presented. The measured behavior is then compared with the predicted behavior using a finite element model of the excavation. The comparison shows a good agreement in a location where the soil profile is well defined. However, differences in the magnitude of the displacements were observed when the information on the soil profile was incomplete due to the variability of the deposits on site.
