考虑到地下水流经各层的面积、流量和渗透系数的关系,运用地下水动力学理论,推导在隔水底板水平、无限补给和直线补给边界潜水含水层中,非完整型隧道涌水量计算公式的综合渗透系数。用三种隧道涌水量计算方法,分别代入综合和几何平均渗透系数,计算雪峰山隧道两区段涌水量,与实测涌水量进行对比,结果表明:新的综合渗透系数的算法预测隧道涌水量具有一定的实用价值。
Taking into account the relationship between groundwater flow through each floor area, flow rate and permeability coefficient, groundwater hydrodynamics theory is used to deduce the calculation formula of water inflow from non-intact tunnel in aquifers with infinite floor, infinite recharge and linear recharge boundary Integrated permeability coefficient. Computation of water inflow in the two sections of Xuefeng Mountain tunnel by using the calculation methods of three kinds of tunnel water inflow, respectively, into the comprehensive and geometric mean permeability coefficient, compared with the measured inflow, the results show that the new comprehensive infiltration coefficient algorithm predicts that the tunnel inflow has Certain practical value.
