摘　　要：径流模数法是估算隧道涌水量常用方法之一,其中最重要的水文地质参数是径流模数,它与隧址区泉流量、溪沟水流量及汇水面积密切相关。目前经常出现在隧道涌水量计算中引用区域地下水径流模数作为计算参数,造成估算错误的情况,以浪拉山隧道为例,介绍隧址区地下水径流模数的取值过程及采用径流模数法估算隧道涌水量的方法,较为准确地获得了隧址区径流模数值。计算成果可作为隧道施工排水设计的依据之一。Runoff modulus method is one of the common methods to estimate the tunnel inflow.The most important hydrogeological parameter is runoff modulus.It is closely related to the spring flow,stream and gully water flow and catchment area in the tunnel site.At present,geologists often use regional groundwater runoff modulus as calculation parameters in tunnel inflow estimation,which leads to the wrong estimation.TakingLanglashan tunnel as an example,this paper introduces the process of groundwater runoff modulus value in the tunnel site area and the method of estimating tunnel water inflow by runoff modulus method.Its principle and working method can provide reference for other similar projects.
