膨胀土滑坡成因及其边坡稳定分析方法探讨
Landslide genesis of expansive soil slope and slope stability analysis method
摘要
Abstract
Various scaled landslide of expansive soil channel slope frequently occurred in the construction of Middle Route Pro-ject of South-to-North Water Diversion, so it is necessary to conduct investigation aiming at the landslide genesis and configu-ration. From the revelation of excavation, it is concluded that the external causes of slope landslide are excavation unloading, co-alescence of fissure, infiltration of rain, creep along gentle direction, and the internal causes are fissures concentration belt, dep-osition interfaces as well as lithology interfaces. The channel slope stability analysis is implemented using rigid limited equilibri-um method and grid search modes considering fissure combination, the calculation results show that the presented slope stability method is reasonable.关键词
