摘要
使用收敛观测法监测了某铁矿采区水平巷道开挖后围岩位移变化情况,并对采区水平巷道建立有限元模型,模拟巷道开挖后围岩应力、应变状况,通过巷道变形监测及数值模拟结果的对比验证了围岩变形机理的结果。
The convergent observation method was used to monitor displacement variation status of surrounding rock after excavation of level tunnel in the mining area of an iron mine. A finit element model of level tunnel in the mining area was established to simulate stress and strain status of the surrounding rock after excavation of the tunnel. Contrast of tunnel deformation monitor values and data simulation resuits verified the results of deformation mechanism of the surrounding rock.
