盾构隧道横向联络通道的明挖施工方法研究

Study on Open Excavation Construction Method for Transverse Connecting Passage of Shield Tunnel

在分析现有盾构隧道横向联络通道技术的基础上,为满足现有规范、标准设置横向联络通道的规定要求,弥补现行主线盾构隧道之间施工横向联络通道存在施工难度大、安全风险高、建设周期长及工程投资高等问题,介绍了一种工艺简单、安全可靠的联络通道施工方法,可大大降低联络通道施工风险与工程造价,有较大推广应用价值。

Based on the analysis of the existing shield tunnel transverse connection channel technology,in order to meet the requirements of the existing specifications and standards for setting the transverse connection channel,and make up for the existing problems of the construction difficulty,high safety risk,long construction period and high project investment in the construction of the transverse connection channel between the main line shield tunnels,this paper introduces a simple,safe and reliable construction method of the connection channel,It can greatly reduce the construction risk and engineering cost of the connecting passage,and has great promotion and application value.
