多因素控制下的城市地下道路总体方案设计

Overall Scheme Design of Urban Underground Road under Control of Multiple Factors

城市地下道路适应城市交通立体化、集约化、生态化的发展方向,成为区域交通的重要组成部分,但在建设过程中,受地下空间复杂性、控制因素多样性的影响,其总体方案设计是一个多目标决策的过程。以武汉谌家矶大道地下道路总体方案设计为例,分析了地下道路建设的控制因素,并从隧道工法分析、横断面方案比选、纵断面方案设计等方面系统地阐述了地下道路总体方案研究过程,可为相似条件下的相关工程提供借鉴和参考。

Urban underground roads adapt to the three-dimensional,intensive and ecological development directions of urban traffic,and become the important part of regional traffic.But in the process of construction,due to the complexity of underground space and the diversity of control factors,its overall scheme design is a process of multi-objective decision-making.Taking the overall scheme design of Wuhan Shenjiaji Avenue Underground Road Project as an example,the control factors in the construction of underground roads are analyzed.The research process of the overall scheme of the underground road is expounded systematically from the aspects of tunnel construction method analysis,cross-section scheme comparison and selection,and vertical-section scheme design,which provide the reference for the relative projects under the similar conditions.
