摘要
综合考虑地质因素、采空区要素特征、高速公路因素,选取稳定性评价指标,然后结合R聚类与变异系数对评价指标进行定量筛选,构建出山西某高速公路下伏小窑采空区稳定性评价指标体系;最后基于层次分析法和信息量法进行小窑采空区稳定性评价。评价结果与现行规范评价结果具有较高的一致性,表明该评价方法对小窑采空区建设场地的稳定性评价具有较好的适用性。
Comprehensively considering geological factors,key factor characteristics of mined-out areas,and expressway factors,stability evaluation indexes were chosen.Combining R clustering and variation coefficient for quantitative screening of evaluation indexes,a stability evaluation index system of small pit mined-out areas underneath an expressway in Shanxi was constructed.The stability evaluation for the small pit mined-out areas was performed based on the analytical hierarchy and informativeness methods.The evaluation results of the system were in good agreement with those of the current specification,indicating that this evaluation system had good applicability to the stability evaluation of the construction site in small pit mined-outareas.
