Comparison Of Two Ground Modification Techniques To Reduce Settlement, Kenneth R. Bell, John R. Davie

International Conference on Case Histories in Geotechnical Engineering

At the La Rosita Power Plant site in Mexicali, Mexico, a 3-m thick layer of loose very fine sandy silt was encountered at about 7.5 m depth. Settlement calculations performed for the heavier (150 to 200 kPa) settlement sensitive structures indicated values of up to 65 mm, compared to an allowable settlement of 50 mm. During the design of the base plant, various options for limiting settlement were reviewed. Based on a cost and schedule review, jet grouting of the loose silt layer was chosen. The predicted post-grouting foundation settlement was approximately 35 to 40 mm. During construction of the …

Measured pile capacities from the static load tests were compared to predicted pile capacities, which were obtained from empirical design methods employing laboratory and in-situ …


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

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 …

Due to the unique geotechnical characteristics at the site, potentially large deformation and slope stability were concerns during the planning and development of the landfill due to the expected high rates of waste placement. Slope stability and finite difference analysis were performed to develop adequate filling plans to cope with the expected …


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 …

On August 13, 2000, a massive landslide occurred in Northern New Jersey following an extreme rainfall event during which at least 381mm (15 in) of precipitation fell during a 4-day period. The composite earth slide-earth flow, with an estimated volume of 22,800 m3 (29,821 yd3) traveled up to 365 m (1200 ft) in a short period. While landslides do occasionally occur along the coastal bluffs of the Atlantic Coastal Plain, slides of this magnitude are uncommon in the glacial soils of the New Jersey Highlands section, where the slide occurred. A geotechnical investigation was undertaken to identify the causative factors …


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 …

Observations Of Site Amplification And Liquefaction In The Jun 23, 2001, Southern Peru Earthquake, Adrian Rodriguez-Marek, Joseph Wartman, Pedro C. Repetto, Jennifer L. Williams

International Conference on Case Histories in Geotechnical Engineering

The Mw 8.4 Southern Peru Earthquake of June 23, 2001 caused extensive damage in a widespread area in southern Peru and northern Chile, including several important population centers. Damage in some of these cities was correlated with local soil conditions and topography, suggesting the influence of local site amplification effects in damage distributions. The earthquake caused numerous instances of other types of geotechnical related ground failures, including liquefaction and lateral spreads in river valleys, seismic compression of highway fills, and slope failures. This work focuses on case histories documenting site amplification and liquefaction in the Southern Peru earthquake. Among …
