| 摘 要： | 为探讨用数值方法模拟地震孕育、发生、发展动态过程的途径，从线性流变体介质内制约质点运动的运动方程出发，导出了模拟地震孕育、发生、发展动态过程的三维有限元方程及程序。还给出了模拟进程中地震孕育、发生、发展过程的约束条件，使得可以用同一个程序完整地模拟地震孕育、发生、发展的全过程，为地震过程本质的认识以及物理预报的实现提供了一个潜在的新手段。

| Abstract: | A method of simulating the pregnant, generation and development process ofearthquakes is discussed in this paper. From motion equation of particle moving inmedium with linear rheological property, we derived the equation of 3D finite elementwhich can simulate the whole dynamic state of earthquake's pregnant generation anddevelopment. The constraint conditions which indicate pregnant, generation anddevelopment of an event were also derived. It makes posibility to use one program tosimulate the whole dynamic state of earthquake's evolving. The papor offers a newpotential way to understand earthquake's nature and to realize physical earthquakeprediction. |
