海底隧道工程在国内还是刚刚起步，正在施工的海底隧道有两条隧道，其他还处于研究之中。作为隧道工程新技术，有许多问题需要隧道专家们来共同合作加强研究，以推进海底隧道工程技术在我国的发展。根据青岛胶州湾海底隧道的设计文件，结合国内各位隧道专家提供的审查意见，提出海底隧道防排水有关方法以供各位借鉴。

The subsea tunneling technology in China is just in its starting stage. At present 2 subsea tunnels are under construction in China and the other subsea tunnels in China are still in research stage. As one of the new tunneling technologies, the subsea tunneling technology has many aspects for which cooperative researches by the tunneling experts are needed so as to boost the development of the subsea tunneling technology in China. On basis of the design documents of Jiaozhouwan subsea tunnel in Qingdao and the recommendations of the tunneling experts in China, the author makes some proposals on the waterproofing and drainage of subsea tunnels in the paper, which can provide reference for the tunneling colleagues.
