The safety of road embankments is mainly assessed in the engineering practice by limit equilibrium analyses. Locating the critical slip surface of embankments and calculating the corresponding factor of safety is a crucial task. In this paper, the continuous ant colony optimisation algorithm is used to analyse the stability of slopes with non-circular slip surfaces. To illustrate the proposed procedure, one example from published literature and another engineering case study of a landslide at a road construction site in India is analysed. This latter study is supplemented by the results of geotechnical investigations performed before and after the failure of the embankment. The results demonstrate that the proposed technique identifies correctly the critical slip surface and can thus be used for engineering applications.

蚁群优化技术在印度东部路堤破坏中的边坡稳定性分析

在工程实践中,主要通过极限平衡分析来评估路堤的安全性。定位路堤的关键滑移面并计算相应的安全系数是一项关键任务。本文采用连续蚁群优化算法对非圆滑面斜坡的稳定性进行分析。为了说明拟议的程序,分析了一个来自公开文献的例子,以及一个印度公路建设工地滑坡的另一工程案例研究。后一项研究由路堤破坏之前和之后进行的岩土工程研究结果补充。结果表明,所提出的技术能够正确识别出关键的滑动表面,因此可用于工程应用。
