摘要
The authors build 140 single homogeneous soil profiles by using four types of soil, such as clay,silt,sand and gravel. The results show that the surface peak acceleration, platform value of the acceleration response spectrum of different soil increase with thickness of overburden layer, then gradually decreased after reaching the peak. The thickness corresponding to the maximum peak is different. The difference of amplification factor between the medium soft site and medium hard site which are in the same site typeⅡ is obvious.
