Abstract

In the numerical simulation of the amplification effect of long-term seismic motion in basins, changes in basin parameters often have a relatively significant impact on the simulation results. Based on a simplified model of buried basin structure in North China, this paper conducted a sensitivity analysis of the impact of basin related parameters on the amplification effect of long-term seismic motion. The results showed that (1) the depth of the basin and the value of shear wave velocity at the base of the basin significantly affect the amplification effect of long-term seismic motion in the basin, they are sensitive parameters; (2) The influence of basin basement density and basement P-wave is not significant and belongs to micro sensitive parameters; (3) The Q value of the basin basement has almost no impact on the basin amplification, so it is an insensitive parameter.
