摘要

以极限平衡理论和传统的安全系数方法为基础，将可靠度理论引入尾矿坝稳定性分析中。通过敏感性分析和可靠度计算分析发现，尾矿材料的内摩擦角的变异性将显著地影响尾矿坝稳定性分析的可靠指标，重度的变异性对可靠指标的影响大于粘聚力的变异性的影响。简述了尾矿坝稳定性分析中利用可靠度理论的重要性，并建议在尾矿坝的可靠度分析中，将尾矿材料的抗剪强度指标c，和重度作为基本随机变量。

Abstract

Based on the limit equilibrium theory and traditional safety factor method

the reliability theory is introduced to analyze the stability of tailings dam. By the analysis of sensitivity and reliability of a typical tailings dam

it is found that the variation of friction angle obviously affects the reliability index and the variation of bulk density has a more obvious effect than the variation of cohesion. It is very important to use the reliability theory in the stability analysis of tailings dam. The shearing strength indexes c

and bulk density taken as essential random variables in the reliability analysis of tailings dam is suggested.
