地质勘探钻孔是获取工程地质信息的最直观的形式，也是地下工程勘测阶段最主要的手段之一。特殊地形条件下的勘探钻孔却给地下工程的施工带来了不利影响，结合工作实际，就水中地质勘探钻孔给隧道施工带来的危害和处理方法进行了探讨。

 Complete and detailed geology exploration by means of borehole drilling in the job site is one of the necessary and effective measures taken during the construction of municipal underground works. During the construction of river/sea crossing tunnels, nonstandard geology exploration may cause lots of hidden troubles to tunnel construction or tunnel structures. In connection with engineering practice, the article describes the harm on the tunnel construction induced by geology exploring borehole drilling in water, which can provide reference for similar works.
