从受力状态判定滑坡体的类型是滑坡体合理治理的前提。针对涔天河扩建工程雾江滑坡体的滑坡类型问题,首先对滑坡体地质特征和边坡原型变形监测进行了分析;然后以力学参数地质建议值及室内试验参数为基础,对4个典型剖面分别进行岩土参数的综合反演,再用摩根斯坦-普赖斯法建立计算模型进行稳定性分析。分析表明:雾江滑坡体以缓慢蠕滑变形为主,滑坡前缘浅层拉裂坍滑可能性较大,而滑坡整体快速滑动的可能性较小;水库蓄水前和蓄水后,坡脚处于薄弱区,最易率先发生滑动并牵引其他滑体相继发生滑动,从而判定雾江滑坡体属于牵引式滑坡。
Determining the type of landslide body from the state of stress is the premise of rational management of landslide body. In view of the landslide type of the Kunjiang landslide in the extension project of Qiongtianhe River, the geological characteristics of landslide body and the deformation monitoring of the slope are analyzed firstly. Based on the geological parameters of the mechanical parameters and the indoor test parameters, The comprehensive inversion of geotechnical parameters was carried out, then the calculation model was established by Morgenstern-Price method to analyze the stability. The analysis shows that the main body of the foggy river is slowly creep deformation, and the shallow layer of the front of the landslide is more likely to be pulled and collapsed, while the whole landslide is less likely to slide rapidly. Before and after the impoundment of the reservoir, Feet in the weak area, the most likely to take the lead in the slide and traction occurred in the other sliding body sliding to determine the fog-landslide belongs to the traction landslide.
