应用Haskell-Thomson方法求解加速度问题,并采用入射波幅值为基准来研究不同土层性质场地对地震波的放大作用,比认为土层下为刚性基岩且基岩处位移(加速度)已知的方法更符合实际。研究了天津市和平区和南开区两场地对加速度地震波的放大作用:分析了不同刚度土层的排列次序对场地整体放大作用的影响,对规范中场地特征周期的取值范围进行了探讨;还提出了由一种场地地震波记录计算另一种场地记录的方法 The Haskell-Thomson method is used to solve the acceleration problem, and the amplitude of the incident seismic waves is used as a reference to study the amplification of seismic waves by different soil properties. It is considered that the underlying bed is a rigid bedrock and the displacement (acceleration) at the bedrock is known. The method is more practical. The amplification effect of acceleration seismic wave on the two sites in Heping District and Nankai District of Tianjin City was studied. The effect of the arrangement order of different stiffness soil layers on the overall amplification of the site was analyzed, and the range of value of the site characteristic cycle in the specification was discussed. A method for calculating another site record from a site seismic wave record is proposed
