| 摘 要： | 巷道断面形状是影响围岩稳定性的关键因素.为研究断面形状对巷道稳定性的影响,对矩形、梯形和直墙圆拱形三种巷道断面形状进行了数值模拟研究,并分析了不同断面形状巷道围岩的应力特征、变形特征和塑性区域.结果表明:直墙圆拱形巷道围岩稳定性最好,梯形巷道次之,矩形巷道稳定性最差.

| Abstract: | Roadway section shape is the key factor affecting the stability of surrounding rock.In order to study the influence of section shape on tunnel stability,three kinds of roadway section shapes,namely rectangle,trapezoid and straight wall round arch,were numerically simulated,and the stress characteristics,deformation characteristics and plastic zone of surrounding rock of different section shapes were analyzed.The results show that the surrounding rock stability of straight wall round arch roadway is the best,followed by trapezoidal roadway,and rectangular roadway is the worst. |
