Qingdao Metro Line 8 was taken as an example for studying the surrounding rock stability of underground tunnel in mud-containing sandstone stratum with pore water. Based on the analysis of deformation and stress evolution law of surrounding rock by simulating three different pore water conditions, the maximum values of vertical displacement (roof subsidence), horizontal displacement (side walls moving closer), vertical stress, horizontal stress and shear stress of the tunnel were finally obtained. The numerical simulation results of tunnel with three kinds of pore water content were applied to the tunnel construction for Qingdao Metro Line 8, and the on-site monitoring results show the deformation of surrounding rock of tunnel roof and side wall is all controlled within the safety range. It is shown that such numerical simulation results provide good reference for the construction of Qingdao Metro Line 8.

为了研究富含孔隙水的泥-砂岩复杂地层隧道围岩稳定性,以青岛8号线泥-砂岩混合地层富水暗挖隧道为例,模拟了3种不同孔隙水情况下的围岩变形及应力演化规律,获得了隧道竖直位移(顶板下沉量)、水平位移(边墙移近量)、竖直应力、水平应力以及剪切应力的最大值。并将3种不同孔隙水情况下的数值模拟结果应用到青岛8号线隧道施工中,通过现场监测发现隧道顶板及边墙围岩变形均控制在安全范围内,该数值模拟结果在青岛8号线施工中具有较好的参考作用。

为了研究富含孔隙水的泥-砂岩复杂地层隧道围岩稳定性,以青岛8号线泥-砂岩混合地层富水暗挖隧道为例,模拟了3种不同孔隙水情况下的围岩变形及应力演化规律,获得了隧道竖直位移(顶板下沉量)、水平位移(边墙移近量)、竖直应力、水平应力以及剪切应力的最大值。并将3种不同孔隙水情况下的数值模拟结果应用到青岛8号线隧道施工中,通过现场监测发现隧道顶板及边墙围岩变形均控制在安全范围内,该数值模拟结果在青岛8号线施工中具有较好的参考作用。

Qingdao Metro Line 8 was taken as an example for studying the surrounding rock stability of underground tunnel in mud-containing sandstone stratum with pore water. Based on the analysis of deformation and stress evolution law of surrounding rock by simulating three different pore water conditions, the maximum values of vertical displacement (roof subsidence), horizontal displacement (side walls moving closer), vertical stress, horizontal stress and shear stress of the tunnel were finally obtained. The numerical simulation results of tunnel with three kinds of pore water content were applied to the tunnel construction for Qingdao Metro Line 8, and the on-site monitoring results show the deformation of surrounding rock of tunnel roof and side wall is all controlled within the safety range. It is shown that such numerical simulation results provide good reference for the construction of Qingdao Metro Line 8.
