济南市黄岗路穿黄隧道总体设计与关键技术

General Design and Key Technologies of Huanggang Road Yellow River Tunnel in Jinan

摘要:

济南市黄岗路隧道是目前内地在建直径最大的盾构隧道，穿越地上悬河黄河。结合悬河保护要求高、盾构掘进距离长、承受水压大、开挖断面大、工作井深度深、建构筑物及环境保护要求高等特点，从隧道功能定位、城市客运专用隧道技术标准选取、隧道平纵断面设计、横断面布置及两岸接线考虑等方面，对隧道总体设计方案进行综合分析，介绍关键技术问题设计方案的解决方案，对提高我国城市客运专用隧道、大型水下盾构隧道及穿越黄河隧道建设水平具有重要参考意义。

Abstract:

Huanggang Road Tunnel in Jinan is the largest shield tunnel in diameter under construction in China now, which will cross Yellow River by suspending on the ground. Combined with the high requirements for suspended river protection, long shield tunneling distance, large bearing water pressure, large excavation section, deep working shaft, and high protection requirements for buildings, structures and environment, the general design scheme of the tunnel is comprehensively analyzed from the aspects of tunnel function location, the technical standard selection for tunnel special for the urban passenger traffic, the plane and vertical section design of tunnel, the cross section layout of tunnel, and the two-bank connection. The solution for key technical problems are introduced, which has a significant reference for improving the construction level of urban passenger traffic tunnel, large-scale underwater shield tunnel and tunnel crossing Yellow River.
