边坡的稳定性问题关系到人类生命财产安全以及工程本身的安全和效益,对其稳定性进行分析评价具有重要意义.本文通过FLAC3D数值模拟软件、采用强度折减法对武安发电厂的人工岩质边坡进行了稳定性分析.列举了边坡稳定性分析的三种失稳判据,并计算了相应的安全系数.分析结果表明,该人工岩质边坡基本稳定,与极限平衡方法比较,所得结果相差不大,说明强度折减法应用于边坡稳定性分析是可行的.此外,本文对该人工边坡的施工方案进行了重新设计.经验算,设计后的边坡依然处于稳定状态,但却大大减少了边坡的开挖量,提高了工程的经济效益.

@@@@?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.
