摘    要:As a kind of transportation mode for crossing channels,undersea tunnel has incomparable advantages for its directness,convenience,fastness,insusceptibility to weather conditions,and smaller influences on environments.In recent years,with the development of undersea tunnel construction,the design and construction technologies have been greatly enhanced.The first undersea tunnel in China has just been built.Waterproofing is the key technique of undersea tunneling.A new concept of waterproofing scheme of grouting,sealing,draining and divided sections was adopted in the construction of the tunnel based on the researches,the in-situ geological features,the astuteness of the current technology,and the cost of construction.The structural details of the sealing and draining system are introduced to illustrate the salient features of the new waterproofing technique.It is hoped that experiences described in the paper can offer guidance for the construction of the extensive undersea tunnels in the coming years.

关 键 词:undersea  tunnel  waterproofing  sealing-draining  system
