吾排隧道涌水量预测及突水防治分析

Water Inflow Forecast and Water Bursting Prevention Analysis of Wupai Tunnel

文章为预测吾排隧道涌水量,在收集区域地质资料和初步勘察资料的基础上,综合运用了调绘、钻探、物探等手段,分析了隧道隧址区的水文地质条件,并采用入渗系数法、径流模数法和地下水动力学法对隧道涌水量进行了计算,提出了隧道施工中出现突水现象的防治措施。

In order to predict the amount of water inflow of Wupai Tunnel,based on collecting the regional geological data and preliminary survey data,and through comprehensive use of methods such as annotation,drilling,and geophysical exploration,this article analyzed the hydrogeological conditions of such tunnel zone,used the infiltration coefficient method,runoff modulus method and groundwater dynamics method to calculate the water bursting amount of the tunnel,and proposed the prevention and control measures for the water bursting occurred during tunnel construction.
