摘要
以青岛地铁苗同区间隧道为依托,通过现场监测和数值分析,探讨了无排水和排水两种状况下,隧道围岩内地下水压力的变化情况,指出选择适当的防排结合型隧道不仅减少了地下水压力对衬砌结构的影响,而且提高了隧道运营期间的安全性。
Taking Qingdao subway Miaotong tunnel as the background,through field monitoring and numerical simulation,the paper explores groundwater pressure changing conditions within the surrounding rock with and without drainage,and points out that： selecting suitable drainageprevention combined tunnel will not only reduce the influence of groundwater pressure upon masonry,but also improve the tunnel safety during the operation period.
