| 摘 要： | 舟山灌门海底隧道跨越灌门水道，是岱山县连接舟山本岛的关键节点工程。前期地质勘探查明海底隧道选址区域平均水深达到35 m，最深处达到52.8 m，海床底部起伏频繁，水深悬殊较大，同时，海床底部及两侧岸上存在3条大规模地质断层破碎带，岩质岩性及围岩破碎状态对隧道施工方案有较大影响。综合比较拟定的2个方案施工难度与工程运营维护的风险以及整个工程规模，选择合理的海底隧道方案。

| Abstract: | Guanmen subsea tunnel in Zhoushan is the key work of the project connectiing Daishan County and Zhoushan Island. The tunnel crosses Guanmen watercourse. The geological investigation reveals that the average depth of the water at the tunnel site is 35 m, with the maximum depth reaching 53.8 m. The sea bed at the tunnel site fluctuates dramatically and the water depth varies greatly. Furthermore, there are 3 large scale fracture zones at the tunnel site, where the rock conditions have great impact on the tunnel. In the paper, comparison and contrast is made between two subsea tunnel options, i.e., subsea tunnel constructed by drill and blast method and that constructed by shield machine. In the end, the option of subsea tunnel constructed by shield machine is proposed. |
