| 摘 要： | 采用有限单元法,分别对锚杆支护和锚注支护两种方式进行了数值模拟,对两种条件下围岩位移、应力以及巷道周围的塑性区的变化情况进行了分析,结果表明锚注支护可以显著地提高围岩强度及支护体系的承载能力.减小巷道的位移变形以及塑性区的大小,有利于维护巷道的稳定性.

| Abstract: | By using finite element program,bolt supporting system and bolt-grout supporting system are simulated respectively,and the displacement,stress and plastic zone of two supporting system are analyzed.The results indicate that the strength and bearing capacity of surrounding rock for bolt-grouting roadway are greatly increased,displacement and plastic zone of roadway are decreased,which is helpful for controlling the deformation of roadway. |
