备注

利用基于FEPG的有限元新模型,从动力学的角度对地震中断层的破裂过程进行了研究,探讨其对边坡的位移场、应力场的动态影响,从而用数值模拟的方法印证了现有的地震滑坡动力学模型理论。

Using a new finite element model based on the Finite Element Program Generator,we research the fault rupture process in the earthquake from the viewpoint of dynamics, and discuss the dynamic effect on displacement field and stress field of slope from the new model.Therefore we use the method of numerical simulation to prove the existing earthquake-inducing landslide dynamics model theories.
