| 英文摘要 | A new procedure based on the approximation to the total normal pressure along the slip surface is developed to Compute the factor of safety of slopes for slip surfaces of all shapes. By taking the whole sliding body, instead of an individual slice, as the loaded object, all the equilibrium equations are formulated according to the three-moment equilibrium conditions rather than the two force equilibrium conditions and one-moment equilibrium condition. The system of nonlinear equations deduced in this way is well-scaled and enjoys excellent numerical properties such as the existence of solution with a positive factor of safety, a nearly unlimited scope of convergence and a rapid convergence rate associated with the Newton method. In the case of phi(u) = 0-the Situation where no drainage and no consolidation are involved, furthermore, the system has a unique solution and the factor of safety has an explicit expression. Some typical examples are analyzed to demonstrate the numerical properties of the proposed procedure. Copyright (C) 2009 John Wiley & Sons, Ltd. |
