摘　　要：采用FEM与BEM耦合技术对华丰矿受采动影响的底板及两帮为煤层的锚网支护顺槽巷道围岩稳定性进行数值模拟。结果表明 ,巷道的两帮及底板破坏范围大 ,变形严重 ,特别是底板的鼓起变形 ,是巷道围岩控制的重点。数值模拟结果与实际情况基本吻合 。The stability of tunnel surrounded weak rock affected by mining pressure in Huafeng Mine is simulated by using the coupling method of FEM and BEM The results show that the fracture and deformation are serious in walls and floor, the protrusion of floor is the key problem in the underground engineering The simulation result is consonant with practice, and the floor reinforcement by effective ways is necessary
