摘　　要：探讨了边坡滑动面搜索的各种优化方法 ,并以边坡工程的可靠性分析为基础 ,从静态分析和动态分析两方面来对边坡工程及各治理方案进行经济风险分析 ,基于投资最省的原则确定边坡适宜的可靠性指标和最佳治理方案 ,从而克服了边坡工程可靠性分析和设计时无规范可依的状况。矿山边坡动态经济风险分析的评价指标宜采用净现值指标 。Various optimal methods in searching sliding surface are summarized; the acceptable reliability index and the optimum reinforcement scheme are determined by the economic risk method from both static and dynamic facets, which is based on reliability analysis of slope and the minimum expense principle. So, the previous difficulty in slope reliability analysis and design of reinforcement measures is overcome. It is reasonable to take the net current value for appraisal of slope on the open pit in dynamic economical risk analysis, while the present value of cost for ordinary slope.
