摘要
为了使用轴对称解计算设置防水板和排导系统的复合式衬砌的隧道涌水量,假定隧道二次衬砌均匀渗水,从隧道涌水量不变的角度,通过反演分析得到复合衬砌的一个量化修正渗透系数K*l.通过六盘山特长隧道实际工程验证了这种方法的可行性及准确性,为复合衬砌涌水量计算提供了有利条件.
Assuming that the two uniform seepage tunnel lining and constant water inflow,the water inflow was calculated in the tunnel with composite lining waterproofing sheet and drainage system by the water inflow axisymmetric solution.Through the back analysis,aquantitative correction coefficient of permeability of composite lining K＊is obtained,the feasibility and accuracy of this method is verified by the actual project Liu-pan mountain long tunnel,providing favorable conditions for the composite lining inflow calculation.
