| 英文摘要 | On the basis of the global analysis method of slope stability, a nonlinear optimum model is proposed for the location of the critical slip surface. In this method, both the factor of safety and vertical coordinates of discrete points on the slip surface are taken as independent variables, and the factor of safety as the objective function, with the constraints including the global equilibrium equations and convexity on the critical slip surface. For non-homogeneous slopes, a smoothing scheme is proposed. Thus the optimization problem can be solved by the classic gradient-based algorithms. The examples show that the proposed method enjoys excellent numerical stability. |
