摘要
在库岸边坡稳定性分析中,按传统的滑坡稳这定性计算方法搜索滑面,本身就是一项繁琐的工作,库水位变动的影响使问题变得更加复杂。数值分析方法在这方面就体现出其优越性。本文采用专业岩土工程软件FLAC3D计算软件,在枯水期和洪水期对杨家坝滑坡进行了分析,研究了两个时期滑坡的变形与受力状态,判定了滑坡的稳定性。结果表明,利用数值方法分析库岸边坡稳定性的方法是值得借鉴的。
In the slope stability analysis of Reservoir Bank, according to the traditional method of calculating landslide stability to search sliding surface, itself is a tedious work, and the effects of changes in the water level make this problem more complex. Numerical analysis methods reflect its advantages in this area. In this paper, using professional geotechnical engineering software FLAC3D calculation software to analysis the Yangjiaba landslide in the dry season and floods, research of two periods landslide on the deformation and stress condition, determine the stability of the landslide. The results showed that the numerical method is worthy means in landslide stability calculation.
