Application of Response Analysis Methods on Evaluation of Liquefaction Potential of Loess Site
摘要
Abstract
The response analysis method is a synthetical way for evaluating liquefaction potential of saturated soil, based on thd dynamic triaxial test result analysis combing with the earthquake share stress time history. In this paper, the dynamic triaxial test for the undisturbed loess samples from a loess site at Shibei tableland in Guyuan city, Ningxia Autonomous Region is done, and the liquefaction potential of the saturated loess is evaluated by using the response analysis method. The result show that the loess will be light liquefiable under seismic intensity of VII, will be middling liquefiable under seismic intensity of VIII, and will be completely liquefiable under seismic intensity of IX. The result is in consistency with true liquefaction damages in this region in 1920 Haiyuan earthquake. It is proposed that the response analysis method can wildly used in the construction projects of the loess region.关键词
