中文摘要: 在开展循化县查汗都斯水库滑坡野外调查及工程地质调查的基础上,简述了滑坡的发育特征、探讨了滑坡的形成条件,进行了稳定性分析。研究表明,地形地貌、地层岩性、地震活动及降水是该滑坡形成的主要因素。本文采用毕肖普法对该滑坡按天然状态和饱水状态两种工况进行稳定性计算,采用ANSYS软件进行二维数值模拟分析,所有结果均显示该滑坡目前处于基本稳定-稳定状态。建议对滑坡进行必要的监测或群测群防。
Abstract:Based on the field work and engineering geologic investigation of Chanhandusi Reservoir Landslide in Xunhua County, this paper focuses on the development characteristics, formation conditions and stability analysis of this landslide. The result shows that this landslide is mainly influenced by landforms, stratum lithology, earthquake and hydrology. ANSYS is used for the stability analysis, which suggests that Chahandusi Reservoir Landslide is currently under stable state. It is necessary for landslide monitoring.
