美姑河洛渣滑坡稳定性分析

Stability analysis of Luozha landslide by Meigu River

水库库区内的滑坡对水利工程的威胁历来备受关注。影响坡体稳定的因素很多,而蓄水往往是导致库岸失稳的主要激发因素。滑坡稳定性评价工作各个环节的侧重点各不相同,如何能够做出正确的结论,就显得极为关键。重点通过现场调查,充分分析滑坡的工程地质条件,重视岩土参数的选取,以定性分析为主,并借助多种计算手段,得到关于美姑河洛渣滑坡稳定性分析定量化的评价结果。

The threat of landslides in reservoir area to the water conservancy project is emphasized by geologists. Although there are many reasons which can cause the slope to slide, the water storage of reservoir is a major reason. There are many viewpoints about the stability assessment of landslides, and how the right one can be chosen from many viewpoints is very important. Based on the careful field-work and qualitative analysis, this paper presents a series of calculation method and corresponding assessment result about stability analysis of Luozha landslide by Meigu River.
