A conveyance water shield tunnel under the Yangtze River, which was designed for the Jiangsu Changshu Power Plant Co., Ltd., was damaged due to water leakage and submersion. In order to complete the engineering, the shield tunnel should be repaired, and the connection between the shield and standpipes should be completed. Therefore, a deep excavati...
A case is presented about damages due to leakage and inrushing water that developed in the segmented pre-casted concrete liner of a shield tunnel under the Yangtze River. Various possible causes were considered to explain the damage mechanism. The opening and distribution due to differential settlement caused by the leakage of biogas or water in th...

... The form of foundation pit supporting structure has great difference in the control of displacement and internal force of adjacent tunnel. The common supporting forms are pile-anchor supporting structure [1][2], double-row pile supporting structure [3][4], row piles (ground connecting wall) + internal bracing structure [5][6]. ...
... These segmental joints make tunnel lining weakened in service performance, especially for mechanical properties and waterproofing behavior. Most water leakage is generally observed at segmental joints (Xu et al., 2016), although other types of leakage points (e.g., hand holes, cracks and grouting sockets) are also found from previous investigation (Wongsaroj et al., 2007). The segmental joints, therefore, are considered key components governing durability and safety of the entire tunnel lining. ...
