摘要
本文对场地土按分层弹性地基土建立了合理的力学模型，通过动力分析，给出了分层弹性地基场地土扭转自振特性及在扭转地震载荷作用下强迫反应的解析解，文中的解析公式为分层弹性的基场地土扭转地震反应分析提供了一种新的解析方法．
In this paper,the reasonable mechanics model are establitshed accordling to lay-er elasto foundation soil of the site.The analytical soltitions for the torsional free vibrationcharacteristics and the coercion responses under action of seismic torsional loading of layer e-lasto foundation soil has been given by means of dynamic analysis,A new analyticalmethod are furnished to torsional seismic response analysis of layer elasto foundation soil inthe paper.
