简要介绍了非连续变形分析的基本原理,分析了新滩滑坡的工程地质特征和发展变化特征,并用非连续变形分析的方法对该滑坡运动的全过程进行了数值模拟,明确了其时空变化规律.非连续变形分析模拟结果表明,中部的姜家坡先发生滑动,继而对上部古滑体产生牵引作用,对下部古滑体产生推挤作用,导致新老崩积堆积区、毛家院和柳林地区的失稳,造成整体滑动.

Based on the general principle of DDA, discontinuous deformation analysis, and the engineering geologic characteristics of Xintan landslide, the numerical simulation is carried out by DDA on the movement process of Xintan landslide. It is concluded that the middle part of the old landslide is reactivated firstly and then causes subsequent failure of the lower part due to the actions of pushing and pulling of slidin...
