摘要
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。
There is no direct relation between the segment step,breakage,and leakage of large diameter river-crossing shield tunnel.However,large grouting volume easily leads to big step at the grouting point.Combined with the rehabilitation project of Shanghai East Yan'an Road Tunnel(the north line),the comparative analysis is made to find the relationship of the backfill grouting thickness with segment step,breakage and leakage.What need to pay attention in tunnel construction is put forward,which can be referred for the similar tunnel construction in the future.
