交通枢纽工程对隧道的影响分析及施工方案研究

Analysis of the Impact of Transport Hub Project on the Tunnel and Construction Scheme Study

本交通枢纽工程是集客运站、地下停车场和人防工程于一体的大型综合交通枢纽,系统构成复杂,设计施工难度大,与既有盾构隧道区间保护红线存在交叉。为有效保护区间隧道、减小工程建设对既有隧道的影响,针对交通枢纽工程对既有隧道的影响分析和施工保护要点进行阐述,以期为同类交通枢纽工程建设提供参考。

The transport hub project is large-scale integrated transport hub with the integration of projects for bus,underground parking and civil air defense. Complex system structure makes it difficult for design and construction. The engineering overlaps the red protection line of existing shield tunnel interval. To effectively protect the interval tunnel,reduce the impact of project construction on the existing tunnel,this article elaborates analysis of impact of transport hub project on the existing tunnel and the construction protection points so as to provide reference for similar transport hub construction.
