摘　　要：准确预测隧道涌水量一直是国内外隧道建设的难点,目前尚无成熟的方法。根据地下水类型及地层性质,再参考隧道区区域地质构造和水文地质条件进行粗略估算,并采用了两种方法对隧道涌水量进行计算,一种是参考《城市轨道交通岩土工程勘察规范》(GB50307-2012)采用条形基坑涌水量公式进行计算,一种则是根据《水文地质手册》(地质出版社1978)第679页达尔西公式计算。经过工程实践表明,隧道涌水量基本上与计算涌水量吻合,计算准确、合理,具有一定的借鉴价值。Correct forecast of water inflow of tunnel is always the difficulty of construction of tunnels at home and abroad, which has no mature method at present. According to the groundwater type and stratum nature as well as rough estimation of regional tectonics and hydrogeological condition of tunnel, the calculation of water inflow of tunnel is performed by adopting two kinds of methods. One is that adopting the formula for water inflow of strip - type foundation pit to perform the calculation based on Code for Investigation of Geotechnical Engineering of Urban Mass Transit （GB50307 -2012）, and the other is that adopting Darcy formula to perform the calculation based on Manual of Hydrological Geology on the page 679 （Geological Publishing House in 1978）. The engineering practice shows that the water inflow of tunnel has no obvious discrepancy from the calculated water inflow basically; therefore, correct and reasonable calculation has certain reference value.
