谈隧道涌水量估算中降水入渗法的应用

On the Application of Precipitation Infiltration Method in the Estimation of Tunnel Water Inflow

在公路工程建设中,隧道工程是重中之重,其涉及的水文、工程及环境地质问题较多,其中隧道涌水量的准确估算对后期施工影响较大。目前在隧道建设中,针对通过潜水含水体且埋藏较浅的隧道,计算方法通常采用大气降水入渗法,该方法在计算上和要求上较为便捷,需要的条件较少,不需要付出太多的外业工作,但是却可以在宏观上大致确定隧道的正常涌水量,然后再结合经验及施工过程中的反馈,就能得到较为贴切的结果,给设计提供必要的基础,因此大气降水入渗法较为宏观可靠,是隧道涌水量估算的重要方法。

In highway engineering construction,tunnel engineering is the top priority,which involves many hydrological,engineering and environmental geological problems.The accurate estimation of tunnel water inflow has a great impact on the later construction.At present,in the tunnel construction,for the tunnel with shallow water content and shallow burial,the calculation method is usually atmospheric drop water infiltration method,which is convenient in calculation and requirements,requires less conditions and does not need to pay too much field work,but it can roughly determine the normal water inflow of the tunnel on the macro level,and then combined with experience and feedback in the construction process,it can get more appropriate results and provide necessary basis for the design.Therefore,the atmospheric precipitation infiltration method is relatively macro it is an important method for the estimation of tunnel water inflow.
