中文摘要:在软弱富水砂层地质条件下,盾构接收施工是盾构法施工过程中主要的重大风险之一,也是整个盾构施工过程中的重大难题之一。本文结合福州地铁2号线桔园洲站—洪湾站区间在软弱富水砂层中盾构接收施工,对盾构接收端头加固、降水施工、盾构接收姿态控制、二次注浆等施工工艺进行阐述,为后续类似地质盾构区间施工提供参考。

Receiving process for earth pressure balanced shield in soft water rich sand formation
Abstract:Under the geological conditions of soft and water rich sand, the shield receiving process is one of the major risks in shield tunneling. It is also one of the most difficulties in the whole work. Based on the shield receiving operations in the soft and water rich sand layer between Juyuanzhou Station and Hongwan Station of Fuzhou Metro Line 2, this paper expounds reinforcement of the shield receiving end, dewatering, control of the shield receiving attitude and secondary grouting, providing reference for shield tunneling in similar geological conditions in the future.
