| 摘 要： | 运用水文地球化学方法对国道213线五指山隧道进行研究。涌水起源和地下水循环特征等方面的研究。结果表明:国道213线五指山隧道涌水属于深循环地下水,进口段隧道涌水主要来自于砂页岩含水层,而隧道出口段涌水化学组成则受控于石膏矿物的溶解;硫、氧同位素组成分析证实五指山隧道主要涌水带均与浅表地下水的直接下渗有关。此研究成果为隧道涌突水的预防和治理提供了理论依据。

| Abstract: | Theory and practice of preventing water inflow into tunnel have demonstrated that the technique of hydrogeochemistry is an effective method. This paper takes the Wuzhishan tunnel of National Road 213 as an example, discusses the application of hydrogeochemistry technique to the source of water inflow into the tunnel and the characteristics of circulation of local groundwater. It is showed that the water inflow into the tunnel is attributed to deeply circulated groundwater. In the entrance part of the tunnel, the water is from the aquifer of shale and sandstone; as for the exit part of the tunnel, the water compositions are controlled by dissolution of gypsum minerals. Analyses of sulfur and oxygen isotope values indicate that the water inflow of the tunnel is mainly related to the direct infiltration of shallow groundwater. |
