摘要
研究了软基SSI体系简化地震响应分析方法。在前期试验和计算结果的基础上,提出了土、结构小刚度比下SSI体系的简化动力计算模型及其参数的反演算法,推导了软基SSI体系简化动力计算模型下的地震响应分析方法。并通过试验软基SSI体系,考证了这一体系下简化动力模型的建模思路。
A simplified seismic analysis method of soft soil SSI system is studied. Based on the earlier stage tests and FEM analysis, a simplified dynamic model with small relative dynamic stiffness ratio of soil to superstructure is put forward, and the inversion solution of model parameters is presented. The seismic analysis method of soft soil SSI system with simplified dynamic model is derived. By comparison of computational solution and test result, the thought of simplified modeling is confirmed.
