利用断裂力学理论及地学中断层走滑移模型,对断层移动和不稳定性做量化分析。将地球垂直切面视为一个半平面含边界裂纹的断裂模型,并对此进行应力分析。对断层中一些参数取不同值时的断层受力进行数值模拟,并绘制应力降的具体走势。
The instability analysis of slip fault with slanting edge crack is given by using fracture mechanics theory and slip fault model.Taking the vertical section of the earth as a fracture model of half-plane containing boundary crack,the stress analysis is given.Some simulations are drafted in some cases,and tendency of stress drop is drawn.
