摘要
在对雷打石滑坡地质环境综合调查的基础上,分析了滑坡体的形态特征及分布范围,用传递系数法和Morgenstern-Price法分别对滑坡的3种工况的稳定性进行分析,最终对滑坡体稳定性进行了综合评价。结果表明:主要由于坡脚开挖和强降雨等因素诱发了坡体产生了整体推移式的剧烈滑移变形,目前滑坡体在天然工况下处于极限平衡状态,在暴雨和地震工况下处于失稳状态。
This paper gives shape and distribution of the Leidashi landslide and makes its stability evaluation by means of transfer coefficient method and Morgenstern-Price method. The results show that the whole produced dramatically push-type deformation induced mainly by the factors such as the excavation of slope foot and heavy rainfall, presently it is in a state of limit equilibrium under natural conditions, and it will be in a state of destabilization under the conditions of heavy rain and seismic.
