摘　　要：在详细的野外勘测基础上,分析了巢湖王家咀老社庙滑坡形态特征和形成机制。通过对土样的室内试验,获得了滑动面初步参数,结合工程类比法和参数反演法取得了该滑坡滑动面的最终计算参数。根据这些最终的计算参数,应用推力传递系数法,在3种情况下计算了该滑坡的稳定性系数。结果显示,该滑坡在自然状态下是基本稳定的,在暴雨和高水位背景下是不稳定的。根据计算结果,提出了对该滑坡以及巢湖沿岸类似滑坡的防治方案和治理建议。On the basis of the detailed field investigation, the paper analyzed the morphological characteristics and formation mecha- nism of the Laoshe temple landslide of Chaohu Wangjiazui. Theinitial parameters of the slip surface were acquired by indoor trial of soil sample, and the final parameters of the slip surface were ob- tained through engineering analogy method and parameter inver- sion method. Based on final calculative parameter, by using trans- fer coefficient method of thrust, its stability coefficient was calcu- lated under three engineering conditions. The result shows that it was basic stable in usual state and unstable in rainstorm and high water level. According to the results the prevention and control plan and treating idea for the landslide and other similar landslide along the coastwise region of Chaohu.
