Stability Analysis on Artificial Rock Mass Slope Based on Using Strength Reduction Method
摘要
Abstract
Rock slope stability is related to human life and property safety as well as engineering security and efficiency. Therefore, the stability analysis and evaluation on rock slope is of great significance. The stability analysis on the artificial rock mass slope of WuAn power plant is carried on in this paper by using the strength reduction method and FLAC3D software. In this analysis, three instability criterions are enumerated, and the corresponding safety factors are calculated. The analysis results show that the artificial rock mass slope is basically stable. Compared with the limit equilibrium method, the difference between the results is not obvious, indicating that analyzing slope stability with strength reduction method is feasible. Otherwise, in this paper, the construction scheme of the artificial slope has been redesigned. After checking calculation, the redesigned slope is still stable. However, the slope excavated volume has been greatly reduced and the economic benefits of the project have been obviously improved.关键词
