摘要
边坡的稳定性分析具有不确定性.以模糊数学为理论基础,建立了露天矿山边坡稳定性的模糊综合评价体系.将边坡的稳定性分为5级,给出边坡稳定性的影响因素,并应用G1法计算各因素的权重,采用公式法和专家评定法确定隶属函数及隶属度.将建立的模糊综合评价体系应用于某露天硫铁矿边坡稳定性分析,评价结果较好地反映了边坡所处实际状态,表明该方法具有一定的实用性,为露天矿山边坡稳定性分析提供借鉴.
An uncertainty is always involved in a stability analysis of slope.Based on the fuzzy mathematics,a fuzzy comprehensive evaluation system for stability analysis of the open mine slope was established.The stability degree of slope was divided into five levels,the factors affecting the stability of the slope were given,and their weights were calculated using the G1 method.The membership function and membership were determined by both formula method and expert evaluation method.The stability of slope in an open pyrite mine was evaluated using the system,and the evaluation results were in good agreement with the actual situation.It is shown that the method has certain practicability and can provide a guideline for similar projects.
