摘要
以国内某大型矿井运输大巷为例,运用大型岩土数值计算软件对断面积基本相等、断面形状不同的2种大断面巷道进行了数值模拟,对比分析其稳定性,得出巷道断面形状对巷道围岩应力场、位移场、变形场、破坏范围的影响,筛选出了该矿条件下稳定性较好的巷道的形状,实现巷道形状的优化选择。
Taking a domestic large transport roadway mine as an example,using large geotechnical numerical calculation software to simulate two large section roadways with basically equal basal area,different cross section shape,through the stability analysis,it is concluded that the influence of cross-section shapes on roadway surrounding rock stress field,displacement field,deformation field,and the damage area,the paper selects good shape under the condition of the mine roadway stability,realizes the optimal selection of roadway shape.
