摘要: 引言爆炸波在土体中的传播规律可用连续介质力学的方法来求解.描述连续介质运动的方程可根据三个基本力学定律导出,即根据质量守恒定律、动量守恒定律和能量守恒定律导出.推导连续介质运动方程的方法有两种:其一是欧拉法,它能给出空间某一点在任意时刻的运动参数和状态参数;另一是拉格朗日法,它能给出每一个质点的运动参数和状态参数.在上述两种方法中,分别有和空间坐标或物质坐标相对应的应力应变量

Abstract: At first ,this paper summarizes the basic contents and theoretical state of soil elastic-plastic constitutive relationship used for blast wave calculations .In particular ,it has given more detailed account of the relatively comprehensive soil hardening plastic model-cap model model which has been developed in the world today .then ,we present a complete preliminary procedure of how to make cap model experiments in a large stress range by the use of our current experimental devices in our country .this is the most important content of the present paper .
