摘要
根据毕肖普法和非线性规划原理 ,对工程实践中最为广泛应用的圆弧滑裂面法 ,提出了一个较为完整的优化数值模型 ,并运用障碍函数法求解了该优化数值模型。为避免陷入“局部优化点” ,运用随机投点法建立了一种全局优化算法。通过工程实例分析 。
According to Bishop's method and non linear programming theory, this paper renders a rather complete numerical model of optimization for method of circular sliding surface applied widely in engineering, and uses obstacle function method to solve it. For avoiding the risk to get in 'part optimization solution', a global optimization method is established through applying a system of randomly obtained points in the paper. The analysis of some engineering examples shows satisfactory results.
