【摘要】 孟家干沟滑坡为岩质边坡,前缘变形严重,坡体表面存在大量变形迹象。在详细调查研究滑坡形成的地质环境条件、滑坡基本特征的基础上,分析评价了该滑坡的形成机制;通过数值模拟分析了坡脚开挖对边坡稳定性的影响;并利用极限平衡法评价了多种工况下稳定性。结果表明,该滑坡在天然条件下已处于欠稳定状态,在暴雨或地震条件下,可能会发生局部失稳。更多还原

【Abstract】 Mengjiagangou Landslide is a rock slope.There is a great deal of deformation of the slope surface.Based on the analysis of the geological environmental conditions and the formation of the landslide,this paper analyzes and evaluates the formation mechanism of the landslide.By using the limit equilibrium method under a variety of conditions,this paper also analyses its assessment of stability.Results show that the landslide in owea steady state under natural conditions and even partial-slippage will happen in times of a rainstorm or an earthquake.更多还原
