摘要
岩层层面对巷道围岩的变形有重要的影响 ,通过对倾斜层状岩层巷道底鼓的数值模拟研究发现 ,造成这种坡状鼓起的原因与机理主要是在巷道顶帮高应力的作用下 。
The bedding joint can influence on the deformations of the surrounding rocks of roadway. The results of the FEM analysis show that the reason and mechanism for the undulated heave are un uniformed separations and strata displacement between the floor beds under the action of the high stresses.
