| 摘 要： | 通过对泔井滑坡的工程（以钻探方法为主）地质勘察评价,对滑坡的物理力学性质及其稳定性有了较为系统的认识：①滑坡体的物质成分主要为粉质粘土加碎、块石;②潜在滑移带均由粉质粘土组成;③对滑坡体和滑移带土的物理力学性质用表格形式进行阐述;④对滑坡体发生滑动的影响因素进行了系统分析;⑤采用传递系数法对滑坡体分多种工况条件进行了稳定性系数和推力计算;⑥结论：在天然状态下,滑坡的稳定系数为1.35,处于稳定状态;在暴雨状态下,加之库区水位达175m时稳定系数为1.01~1.05,滑坡处于欠稳定状态;而在175m回落至145m的过程中加暴雨及地震作用下,稳定系数为0.97~0.98,这时的滑坡处于不稳定状态。

| Abstract: | Through geology investigating and evaluating the Gan jing slope （mainly by drilling）, we have systemetic knowledge about the physiced mechanical properties and the stabilities of the slope slide. （1） The main component of the landslide is silty clay add detritus and rubbles. （2）The latent slip band is all formed with silty clay. （3）The physics mechanics property of the landslide body and the slip band soil were listed in tables. （4）System etically analyzed the influence factors of landslide body. （5）Adopt to deliver the coefficient method and divide various work conditions to calculate the stability coefficient and buck force. （6）The conclusion is： the natural state, the landslide body stability coefficient is 1.35, is in the stable state; under the condition of the continuous high strength rain, and the water level up to 175 meters, the landslide body stability coefficient is 1.01 - 1.05, the landslide is not stable enough; When the water level drop from 175m to 145m, and rain-storm and the earthquake, the landslide body stability coefficient is 0.97 - 0.98, the landslide body is in the unsteady state. |
