在隧道施工过程中，隧道区工程地质和水文地质条件如未能提前查明常常导致围岩失稳、隧道涌水和流土等问题。在这些问题中，隧道涌水较为常见并往往威胁施工人员的人身安全，同时也将影响施工进度且增高工程造价。以二广高速公路跑石界隧道为例，在前期专项水文地质勘察的基础上，通过几种不同的计算方法，对该隧道涌水量进行了计算。通过与实测涌水量的对比，指出各涌水量计算方法的优缺点，根据各方法的适用条件为该隧道的顺利实施提供技术支持。

Due to the uncertainty of hydrogeology conditions,some problems may occur during the tunnel construction, such as tunnel gushing,soil flow,surrounding rock instability,etc.Among these geological disasters,the tunnel gush-ing is common and can threaten the constructor’s personal safety.Furthermore,there will be an increasing cost and a delay in the construction.Therefore,taking Paoshijie Tunnel of Erguang Expressway as an example in this study,on the basis of the special hydrogeology survey for this tunnel and different calculation methods,the water outflow of the tunnel has been calculated.Through comparison between results of actual measurement and theoretical calculation,in this study,it has shown that all the five predicting methods have their own advantages and disadvantages.At last,the technical support is given out according to the applicable conditions of each method for the tunnel.
