边坡可靠性与经济风险性分析及其应用

RELIABILITY ANALYSIS AND RISK EVALUATION OF THE SLOPE ENGINEERING

摘要: 本文在边坡渐进破坏可靠性分析的基本原理和计算方法基础上 ,分析了影响边坡渐进破坏的主要因素 ,对白云鄂博铁矿的主矿边坡进行了二维渐进破坏可靠性计算 ;然后围绕边坡方案的可靠性分析结果 ,把经济决策理论引入边坡的经济分析中 ,结合边坡工程具体特点对边坡进行了投资效益风险性分析。

Abstract: In this paper, the progressive failure probability of the slope of the Baiyunebo Open Pit Mine is evaluated by using Monte Carlo method, based on 2 D reliability model for progressive slope failure. Then based on the calculation results, the risk of investment and benefit is evaluated by applying economic decision theory to slope engineering.
