摘要
在新型城市更新的背景下,修建地下隧道已成为缓解高密度交通路网压力的重要解决方案。但实际设计施工过程中会面临多重挑战,比如隧道排水是否可靠、管线迁改能否保通落地等,此类问题均需系统性研究。以郑州市二七广场隧道工程为例,详细阐述了隧道排水设计以及复杂环境下管线迁改与保通方案。通过对该工程的研究与分析,为同类型地下隧道建设提供了案例支撑及设计新思路。
Under the background of new urban renewal,the construction of underground tunnels has become an important solution to relieve the pressure on high-density traffic networks.However,in the actual design and construction process,the multiple challenges will be faced,such as whether the tunnel drainage is reliable and whether the pipeline relocation can be smoothly implemented and unobstructed.All these issues should be systematically studied.Taking the Zhengzhou Erqi Square Tunnel Project as an example,the tunnel drainage design,and the pipeline relocation and smooth implementing schemes are set forth in detail.The study and analysis of this project can provide the case supporting and new design ideas for the construction of similar underground tunnels.
