上海长江隧道工程建设与施工风险控制

上海长江隧道工程采用φ15.43m泥水气盾构掘进机,一次掘进距离7.5km,隧道直径和一次推进距离均创世界之最。工程难度大、风险高,是上海长江隧桥项目的关键控制节点工程。该文主要介绍了工程概况和超大直径、超长距离盾构掘进施工及其风险控制措施。

Shanghai Changjiang Tunnel Engineering Building and Construction Risk Control

Theφ15.43-m soil-water-air shield tunneling machine is used in Shanghai Changjiang Tunnel Project.The tunneling distance is 7.5 km once.The tunnel diameter and the primary tunneling distance are the first on the world.The engineering difficulty is larger and the risk is high, which are the key control node works of the Shanghai Changjiang Tunnel Project.The article mainly introduces the engineering situation,and the super-large diameter and super-long distance shield tunneling construction and the risk control measures.
