摘要
以台缙高速公路苍岭隧道为例,通过水文地质综合勘探方法,查明隧道不同裂隙发育程度岩体的渗透系数K值。然后利用地下水动力学法、地下水径流模数法对隧道开挖涌水量进行了预测。通过施工检验发现,涌水段位置和涌水量总体较接近,说明预测工作对隧道的施工开挖和排水设计具有指导意义。
Taking Cangling tunnel of Taizhou--Jinyun Highway as an example, the permeability coefficient of rock masses with different joint developments in tunnel are found out by hydrological geology integrated exploration method. Then water inflow in tunnel is forecasted using groundwater dynamics and groundwater modulus bf runoff. Results show that the predicted location where inflow happens and the quantity, of inflow approximate the practical ones, which indicates that the prediction of water inflow is of guidance to design and construction of drainage.
