略阳狮子山滑坡二维有限元分析

当斜坡土体内的剪应力达到或超过其最大抗剪强度时，岩土体将发生破坏，特别当坡体内形成一个不利的、连续贯通的破坏区域时，坡体将会产生滑动破坏从而形成灾害．本从陕西略阳县狮子山斜坡的工程地质背景出发，以滑坡工程地质特征为基础，在分析斜坡变形破坏的形成机制及模式的前提下，采用二维弹塑性有限元与刚体极限平衡法分别从两个方面分析和计算了该滑坡的稳定状态，得出该滑坡存在较多的破坏区,处于不稳定到基本稳定状态,需要采取各种措施进行治理．

Stable Analysis on Shizi Mountain's Landslide in Lueyang by using Two-dimension Limited System Theory

The destroy for the body of sock and soil will happen when the shearing strength in the body of sock and soil of slope reach and exceed the most shear strength for the rock and soil.In particular,the body of the slope will bring glide and destroy to come into being disaster when it forms in the slope to destroying district of bad and continuum transfixion.The geologic setting of Shizi Mountain's slope,and the detail material about the engineering geological character of the landslide were introduced,respectively.Forming mechanism and mode of the slope's deformation and damage were analyzed.In order to estimate the stability of Shizi Mountain's landslide,the stability of the landslide from two aspects by using two-dimension limited system of elasticity and plasticity and limited equilibrium method were analyzed and calculated,respectively.The results suggested that there were a lot of destroying parts in the landslide,and the stable state of the landslide was in a shaky stability to basic steadiness.It needs taking measures to bring it under control.
