摘要
城市综合管廊下穿高铁应结合项目自身特点,充分考虑安全性、可实施性及施工时序的影响,施工时应密切配合与加强监测及检测。该文通过对城市综合管廊下穿高铁方案的研究比选,分析了综合管廊下穿高铁时管廊断面结构布局、施工工艺及其影响,总结了综合管廊下穿高铁时支护方式及综合管廊与高铁框架涵合建的设计思路,并提出了需注意的事项及相关建议。这些施工经验与设计思路,可供同类工程参考。
The project of urban utility tunnel crossing beneath high-speed railway should combine the project's characteristics,fully consider the safety,implementability and the impact of construction time sequence,as well as closely cooperate with and strengthen monitoring and testing during construction.Based on the research and comparison of the schemes for urban utility tunnel crossing beneath high-speed railway,this paper analyzed the sectional structure and layout of utility tunnel,construction techniques and its influence on the mode of urban utility tunnel crossing beneath high-speed railway,and summarized the support schemes for urban utility tunnel crossing beneath high-speed railway and design ideas of co-construction of urban utility tunnel and high-speed railway frame,with noteworthy issues and relevant suggestions presented.
