- Abstract:
-
Taking trapezoidal valley site as the research object,the OpenSees finite element program which is used widely in earthquake engineering was adopted for simulating the deep valley sites,then the influences of different valley slope angle,depth-to-width ratio,overburden thickness on the surface ground motion response spectra were explored,furthermore the corresponding laws of ground motion about the sites were captured.The results show that the slope angle and depth-to-width ratio have no significant influence on the characteristic period of the response spectrum,but have significant influence on the platform value of the response spectrum.The Tab.of correction coefficient of the platform value of ground motion response spectrum is given by mathematical statistical method.
