| 摘 要： | 在对隧道两侧进行水文地质调查的基础上,结合调查区地质环境背景,查明该区水文地质条件。分析不同地层岩性的含水性和富水性,评价地下水的补给、径流和赋存特征,预测隧道开挖时可能发生涌突水的位置。采用狭长水平廊道法、大气降水入渗系数法、比拟法和大气降水入渗法对隧道涌水量进行预算,为隧道施工开挖预防涌突水灾害提供依据。

| Abstract: | The hydro-geological conditions are identified on the basis of the hydro-geological investigation on both sides of the tunnel and its geo-environmental background analysis.Level passage method,precipitation infiltration coefficient method,analogy and precipitation infiltration method are used to calculate gush water amount,which offers a basis for the tunnel excavation. |
