| 摘 要： | 反应分析法是一种基于动三轴试验,并考虑场地地震危险性一种综合性饱和土体液化评价方法。本文对固原石碑塬黄土进行了动三轴液化试验,利用反应分析法对该场地饱和黄土液化势进行评价,并和海原地震中固原石碑塬黄土的实际液化情况对比。研究结果表明利用反应分析法对饱和黄土进行液化势评价的结果与实际震害相符,可在黄土地区建设工程场地地震液化势评价中广泛应用。

| 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... |
