Abstract: A volcaniclastic formation, known as Cangahua, found in the Andes of Ecuador and Colombia is focused on. The deposit is composed of moderately cemented fine sand and silt‐sized particles. A pronounced linear correlation ...

Abstract: This paper focuses on the seismic response of liquefaction sites by evaluating the transient shear strains and strong-motion characteristics at Treasure Island during the 1989 Loma Prieta earthquake (

Abstract: Investigations of liquefaction sites, combining subsurface mapping and evaluation of liquefaction damage, are summarized for four areas in San Francisco affected by 1906 and 1989 earthquakes, where more than 950 borehole ...

Abstract: Welded slip joints, which are used in many high-pressure water transmission pipelines, are vulnerable during earthquakes to axial compressive loads generated by ground movements. This paper analyzes ...

Abstract: The results are summarized for an experimental program involving over 450 direct shear tests of sand‐polymer interfaces. The interface frictional strength was found to increase with soil density and decrease with the Shore ...

Abstract: This paper addresses the base stability of excavations in deep, relatively weak deposits of clay that are supported by earth-anchored tiebacks. Under these conditions there may be the potential for a circular sliding surface ...

Abstract: This paper describes the performance of a tiedback excavation with a soil mixed wall in Boston where underlying marine clay was stabilized by deep soil mixing (DSM) and jet grouting. Lateral and vertical soil displacements, ...

Abstract: This paper summarizes lessons learned about soil stabilization with the deep mixing method (DMM) as it was developed and applied over 10 years during construction of the Boston Central Artery and Tunnel (CA/T). It also ...
