东旱门过江隧道工程设计

On engineering design for river-crossing tunnel at Donghan Gate

通过对东旱门过江隧道工程设计实例进行总结,论述了盖挖逆做法、河底结构防水、新型围护结构及永临结合的支撑体系在场地条件局促的城市下穿隧道中的具体运用,为今后类似工程设计拓宽了思路。

The paper sums up the engineering design cases at the river-crossing tunnel at Donghan Gate,indicates the application of the CCTDM,the structural waterproof at the river-bottom,the new enclosure structure and the supporting system combining the permanent with the temporary ones in the undercrossing tunnel of cities with limited field conditions,so as to broaden the ideas for the design of similar projects in future.
