Based on the plasto-elastic bounding surface model, the dynamic characters of typical clay and silt were studied through several types of laboratory dynamic tests. The parameters of dynamic bounding surface model were given upon the tests. By using a nonlinear procedure for response analysis of horizontally layered sites subjected to multi-directional earthquake loading, the response of acceleration, pore pressure and dynamic stress in Shanghai area under different earthquakes were studied.

在弹塑性边界面模型的基础上，通过试验，研究了上海地区典型粘土和砂性土的动力特性，取得了针对边界面模型的计算参数，并采用多向地震作用下的水平地层弹塑性动力反应分析程序对以深厚软土覆盖地层为特点的上海地区典型的土层断面，以苏南核电站为主的地震输入进行了场地反应分析，在加速度特性、孔压特性和动应力特性等方面取得了相应的结果。

Biot's consolidation theory was used to serve as a frame working with the nonlinear elastic model or with elasto-plastic model in the program. Nonlinear elastic model includes Duncan-Zhang model, Gong Xiannan Ko consolidation model and the model proposed in chapter 2. Elasto-plastic model in the program includes Mohr-Coulomb model, Drucker-Prager model and the bounding surface model developed in chapter 3. The program can be used in cases of plane problem and axisymmtric problem.

FOR，针对软土地基的变形特点，该程序以Biot固结理论为框架，可以进行线弹性，非线性弹性和弹塑性的有限元计算，在非线性弹性模型中包括了Duncan—Chang模型、龚晓南Ko固结模型和本文建立的非线性模型，弹塑性模型中包拓了Mohr—Coulomb模型，Drucker—Prager模型以及本文中建立的边界面模型，该程序可以考虑平面问题也可以考虑轴对称问题。

During testing process, an effective testing system of simulating battle damage has been developed. It consists of high pressed air-gun, an assembled projectile body and bullet-shoe design, an instantaneous velocity measurement system with laser and lens, set-up frame for the specimens, and the projectile trap box.

通过试验研究，一个由高速气炮，弹体与弹托分离机构、连续位移激光测速装置和弹丸回收装置被建立并有效的用于本文的弹丸正撞击试验。
