Discussion on Adjustment Method of the Characteristic Period of Site Response Spectrum with Soft Soil Layer

Twelve site models were established based on the analysis of influence conditions earthquake damage and soft soil layer on-site seismic response. The equivalent linearization response is carried out at different input ground motion levels to discuss thickness buried depth. results show that characteristic period spectrum exhibits a gradual increase as depth or increases. Furthermore, also increases with rise in peak. Moreover, according characteristics thickness, depth, intensity acceleration spectrum, method for adjusting put forward.
