隧道工程中的水文地质勘察与预测

在隧道建设和运营过程中会经常遇到水害,尤其是涌水、突水（突泥）危害性更大,会造成巨大的财产损失和人员伤亡。降低水害影响除了要合理设计、科学施工外,还应重视水文地质勘察工作,为设计提供准确的地质资料,尤其当隧道穿越高水位富水地段时,更应重视涌水灾害,加强科研攻关,广泛运用勘察新技术。以佛岭隧道为例,对隧道涌水量预测常用方法加以介绍,对于隧道工程的水害防治具有重要的参考价值。

Hydro-geological Survey and Forecasting in Tunnel Engineering

Water damages are encountered mostly in the tunnel construction and the operation process. In particular,the hazard of gushing,pouring water（process sludge） which is bigger caused extensive property damage and casualties. In order to reduce the harmful effects of water,besides reasonable design and science construction,the work of the hydro-geological investigation is very important,and the accurate geological data is provided for the design. Especially when the tunnel passes through the water-rich area of high-water level,gushing disaster is taken seriously,the scientific research is strengthened and the new technology investigation is used extensively. Taking Foling Tunnel as an example,the common method of gushing water forecast is introduced. It is important to the prevention of water damage in tunnel engineering.
