一、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
I. INTRODUCTION The law of propagation of blast waves in soils can be solved by methods of continuum mechanics. Equations describing the motion of continuum can be derived from three basic laws of mechanics, namely, the law of conservation of mass, the law of conservation of momentum and the law of conservation of energy. There are two ways to derive the motion equation of the continuum: one is the Euler method, which can give the motion parameters and state parameters of a certain point in space at any time; the other is the Lagrangian method, which can give every The motion parameters and state parameters of a particle. In the above two methods, there are stress strains corresponding to the space coordinates or the material coordinates, respectively.
