武汉市二七路过长江通道工程总体方案研究

Research on Overall Scheme of Wuhan Erqi Road Yangtze River Crossing Project

摘要:

江河是城市发展的重要资源，但也割裂了两岸的交通联系。随着城市的快速发展与扩张，过江交通的需求越来越大，同时由于过江通道的逐步建设，过江资源也越发稀缺。在这种背景下，做好过江通道的总体设计，对于节约过江资源、发挥过江通道的交通作用以及带动城市高质量发展至关重要。结合长江首座双层公路过江隧道武汉市二七路过长江通道工程，首先对项目的功能定位、交通流量预测和建设规模进行了论证，再对桥隧方案进行综合比选，最终从项目的路线设计、平面布置、两岸交通疏解设计、隧道纵断面设计、隧道横断面布置等方面论述了总体设计方案，可供类似工程参考。

Abstract:

Rivers are vital resources for urban development, but also create a divide in transportation links between the two banks. With the rapid development and expansion of cities, the demand for cross-river transportation has increased significantly. At the same time, due to the gradual construction of cross-river passages, these resources have become increasingly scarce. In this context, the overall design of the cross-river passage is of vital importance for conserving cross-river resources, giving full play to the transportation role of the cross-river passage and promoting the high-quality development of the city. In combination with the Wuhan Erqi Road Yangtze River Passage Project that is the first double-deck highway tunnel across the Yangtze River, firstly, the functional positioning, traffic flow prediction and construction scale of the project are demonstrated, and then the bridge and tunnel schemes are comprehensively compared. Finally, the overall design scheme is discussed from the aspects of route design, plane layout, traffic diversion design on both banks, vertical section design of the tunnel, and cross-section layout of the tunnel of the projects, which can provide a reference for the similar projects.
