【Abstract】 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.更多还原
