| 摘 要： | 根据对黄岗滑坡的分析,其属于蠕滑-拉裂型滑坡。本文阐述了滑坡的基本特征,并研究分析了滑坡的成因机制及演化过程;在成因机制分析基础上,采用极限平衡法对该滑坡天然状态及暴雨情况下的稳定性进行了计算和评价;另外,还采用有限元数值分析软件Midas对滑坡进行数值模拟,并对数值模拟成果和传统计算的结果进行对比分析,为滑坡治理设计提供了重要的依据。

| Abstract: | According to the analysis of Huanggang landslide,the creep deformation of landslide type,this pa-per expounds the basic characteristics of the landslide,and has analyzed the formation mechanism and evolu-tion process of landslide formation mechanism.On the basis of the analysis,it uses the limit equilibrium method for the calculation and evaluation of the landslide stability of natural state and rainstorm conditions. In addition,with the finite element analysis software Midas,the numerical simulation of landslide was car-ried out.The simulation results and the traditional calculation of numerical results are compared and ana-lyzed,which provides an important basis for the design of landslide treatment. |
