Abstract: Through the simulation of soil profile and the equivalent linearization procedure, the surface seismic response spectrum was calculated by using the measured value, industry recommended value and standard value of the soil nonlinear dynamic parameter, dynamic shear modulus ratio and damping ratio, respectively.We compare the peak of surface ground motion, the characteristics cycle size of response spectrum and the shape of the response spectrum, in order to evaluate the effect of soil dynamic parameter on surface seismic response.
