摘要
本文根据延安东路隧道南线盾构进洞段工程施工的情况,论述了泥水平衡盾构穿越冻结加固区的施工技术。冻结加固技术的成功应用为盾构顺利穿越超浅覆土的地下管线和盾构进洞奠定了基础。
Based on the construction of approach tunnel wilh the shield in the southern part of the Yanan Road Tunnel in Shanghai,the construction technology of shield passing through area consolidated by freezing was described.Due to the success of consolidation by freezing,it laid a foundation for entering of shield into tunnel and its passing through underground pipelines with shallow cover.It demonstrates the possibility,effectiveness of this technology for construction in soft soil in Shanghai.
