摘要
滑坡的位移变化是一种非线性的过程 ,并在各种因素的影响和作用下表现出各种动力学特征。本文在传统的条分法的基础上 ,采用离散元模型的思想 ,提出一种滑坡位移非线性动力学模拟的方法。最后给出了几种合理的模拟结果。
The process of landslide displacement is a non linear behavior and has its several dynamic characteristics due to the effect of various environmental factors. Based on the conventional slice method, this paper provides a non linear dynamic modeling method for landslide displacement from the conception of discrete element method(DEM). Some reasonable simulation results are given at the end of the paper.
