3D FINITE DIFFERENCE NUMERICAL SIMULATIONS OF EARTHQUAKE FAULT ENDANGERED FIELD
【摘要】 采用显式拉格朗日有限差分法,通过对所建立的张店-仁河断裂的地质构造三维结构模型施加不同的地震波荷载,得到了地震活断层危害场的数值模拟结果,包括各种情况下的变形场、应力场和位移场。数值模拟结果均以图形化的方式显示出来,最后对模拟计算结果进行了分析。
【Abstract】 The explicit Lagrangian finite difference method is introduced in this paper,by imposing different seismic wave load to the created 3D geology model of Zhangdian-Renhe Fault,the numerical simulation results of the near fault disservice field has been obtained under various conditions including deformation field,stress field and displacement field.Numerical simulation results are graphically displayed.Finally the simulated calculation result is analyzed.
