According to the transmission of seismic wave, dynamicpropertyofsoil-structure and energy dissipation, the mechanics and the results of seismic soil-structure interaction are analyzed.
According to the data ofdynamicpropertyof the site soil, the design ground motion parameters of the different level are calculated by the equivalent linear method.
采用一维等效线性化方法，根据场地土动力性能试验资料，确定不同抗震标准下的设计地震动参数。
