摘　　要：排土物料是影响排土场稳定性的最直接的因素,由于力学试验的随机性,很难确定排土物料力学性质中影响稳定性的最主要因素。以某排土场为研究背景,基于地质勘察资料,选取3个典型剖面,对排土物料力学性质中黏聚力、内摩擦角和容重3种敏感因素进行敏感度模拟分析。结果表明,内摩擦角敏感度最高,黏聚力其次,容重的敏感度最低,对排土场边坡稳定性的影响可忽略。研究结果对排土场的初始设计、后续建设和运行具有一定的指导意义。The discharge material is the most direct factor affecting the stability of the waste dump.Due to the randomness of the mechanical test,it is difficult to determine the most important factor affecting the stability of the dumping materials.Taking a waste dump as the research background,three typical sections are selected based on geological survey data,and the sensitivity simulation analysis of three sensitive factors of cohesion,internal friction angle and bulk density in the mechanical properties of dumping materials is carried out.The results show that the sensitivity of internal friction angle is the highest,followed by cohesion,and the sensitivity of bulk density is the lowest,which has negligible influence on the stability of the dump slope.The research results have certain guiding significance for the initial design,subsequent construction and operation of the waste dump.
