大直径盾构越江隧道的错台、破损和渗漏之间没有直接的联系,但若注浆量较大容易导致压注点附近较大的错台。结合上海延安东路隧道北线修复工程,针对隧道壁后注浆层厚度、错台、破损和渗水情况进行对比分析,找出了相互间的内在关系;提出了隧道施工中需要注意的问题。这对今后同类型隧道施工具有参考价值。 Large-diameter shield tunnel cross-river tunnel fault, damage and leakage is not directly linked, but if the larger amount of grouting easily lead to a larger injection pressure near the wrong point. Combined with the northern line restoration project of Yan’an East Road Tunnel in Shanghai, contrastive analysis of grouting layer thickness, fault, breakage and water seepage is carried out to find out the internal relations among tunnels. Some problems that need attention in tunnel construction are put forward. This is of reference value to the same type of tunnel construction in the future.
