Effective stress analysis for the effects of liquefaction condition on ground motions

Abstract

Based on the representative soil layer distribution in Shanghai and its mechanical parameters, the authors select and build a number of computation profiles, the effects of ground water level, silty sand deposit thickness and its depth on the ground surface peak acceleration and its displacement are calculated by means of drained effective stress analysis method incorporating Biot dynamic consolidation equations and a bounding surface hypoplasticity model. Some results are useful. © 2008 Science Press Beijing and Springer-Verlag GmbH Berlin Heidelberg Geotechnical Engineering for Disaster Mitigation and Rehabilitation.
