Research of Soil Layers Amplification Effect Based on Strong Seismic Records and Calculations

This paper states the comparison research of calculation results from program LSSRLI-1 and program SHAKE2000, with the strong seismic records as well as the site soil conditions by using borehole arrays. The analytical results show that the site soil conditions have an amplification effect on the seismic PGA and response spectrum values, however, the actual seismic records are not consistent with the program calculations on the amplification effect. Besides, the site soil conditions also have an altering effect on the predominant period of seismic response spectrum, where actual seismic records and program calculation results of the altering effect are not the same either.
