摘　　要：近年来,高速公路穿越煤矿老采空区的工程案例逐渐增多,如何保障车辆的运行安全是煤矿老采空区上方高速公路建设的关键问题。为此,以武云高速为例,首先选取6大因素、19个因子,构建了II级模糊综合评判模型,其次综合采用标度法和特征向量法确定评价因子的权重,而后结合德菲尔法和散点图法分析研究区域各评价因子的隶属度,最后对武云高速建设场地的稳定性进行评判。评判结果表明:研究区域处于基本稳定状态,通过采取简易抗变形设计即可保证武云高速公路的运营安全。研究成果丰富了煤矿老采空区上方高速公路建设的安全性评价体系,并为相关领域的研究提供了新思路,具有广泛的指导意义。In recent years,the cases of expressway crossing the old goaf have gradually increased.The key problem about expressway construction on the old goaf is how to ensure the safety of vehicles operation.Therefore,taking the Wuyun expressway as a case,firstly,a level-2 fuzzy comprehensive evaluation model is established with 6 elements and 19 factors. Subsequently,the evaluation factors weights are determined by using the scaling method and the eigenvector method.Then,the membership degree of evaluation factors are determined by using the Delphi method and the powder point diagram analysis.Finally,the stability of Wuyun expressway construction site is evaluated.The results show that the study area is basically stable,and the vehicles safety of Wuyun expressway can be ensured by adopting simple anti-deformation design. This research can enrich the safety evaluation system of expressway construction on the old goaf of coal mine,and provide a new idea for the related researches with a wide guiding.
