| 摘 要： | 岩溶区反坡施工的隧道大多需要抽排水,而勘察设计文件仅对隧道分一段或多段进行了涌水量总体预测,工程计量时如何合理确定反坡段涌水量少有研究。针对这一现状,以利万高速齐岳山隧道为例,对勘察设计、工程施工、施工后期3个阶段隧道涌水量预测和计算方法进行了研究,得出隧道反坡施工段合理涌水量的计算方法。

| Abstract: | Most of the tunnels constructed on the reverse slope in karst area need pumping and drainage.However,the survey and design documents only predict the water inflow in one or more sections of the tunnel.There is little research on how to determine the water inflow in the reverse slope reasonably when measuring the project.In view of this situation,taking Qiyueshan Tunnel of Lichuan-Wanzhou Expressway as an example,the prediction and calculation methods of tunnel water inflow in three stages of survey design,engineering construction and late construction are studied.The calculation method of reasonable water inflow in the construction section of tunnel reverse slope is obtained. |
