不同倾斜方式对倾斜液化场地地震响应的影响分析
Influences of different inclination modes on seismic response of inclined liquefiable site
摘要
Abstract
In the study of the failure and large deformation of inclined site caused by lateral flow expansion of soil after seismic liquefaction,different inclined modes will have a certain impact on the test results,but the research results on the impact evaluation of seismic response of inclined liquefiable site are still relatively rare at present.In this study,a numerical model for horizontal liquefiable field is established based on the OpenSees finite element platform according to the completed shaking table tests,and the influences of the model box on the dynamic response of soil are considered in this numerical model,and the validity of numerical model is verified by comparing with the shaking table test results.Then the finite element numerical model for inclined liquefiable site is established based on the horizontal numerical model,and three different numerical models for inclined shear box model,inclined soil in shear box model and inclined soil in rigid box model are established to simulate different inclination modes in the shaking table tests.Through comparison,the dynamic responses of soil calculated by three numerical models under the action of 0.3g Wenchuan earthquake Wolong wave are examined,and the influences of three different inclination modes on the results are analyzed,and some valuable conclusions about the researches on the numerical simulation and shaking table tests of seismic dynamic response of inclined liquefiable sites are shown.关键词
