盾构施工综合管廊设计要点探讨

Discussion on the Design Key Points of Shield Utility Tunnel

现行《城市综合管廊工程技术规范》(GB 50838—2015)中没有针对采用盾构法施工的综合管廊的具体技术规定,通过对盾构施工工法及综合管廊的技术特点进行分析,从入廊管线、管廊断面布置、平纵布置、关键节点(盾构综合竖井)及管廊附属系统等方面,对盾构管廊设计要点进行了探讨,可为后续盾构管廊设计和规范完善提供参考。

The current Technical Code for Urban Utility Tunnel Engineering (GB 50838-2015)does not provide specific technical regulations for the shield utility tunnel. By combining the technical characteristics of the shield construction method and the utility tunnel,the design key points of shield utility tunnel were discussed,which included the urban pipeline into the tunnel,the standard crosssection,the plan and vertical section design,the key node (shield comprehensive shaft) and the accessorial facilities of the utility tunnel,etc. The key points of the paper could provide references for the design of following utility tunnel and specification improvement of current utility tunnel code.
