厦门翔安大桥本岛立体交通组织研究

Research on Three-dimensional Traffic Organization on the Main Island of Xiamen Xiang’an Bridge

对于穿越城市中心区域的主要干道,集约并妥善处理好过境交通与片区交通的关系,关乎到整个通道交通转换的效率,而其中交通组织方式的选择往往由城市景观、周边环境协调性、规划协调性、工程造价等多因素综合确定的。介绍厦门翔安大桥在本岛侧枋钟路特定的控制因素下,通过多因素对长隧道、短隧道及高架等方案进行综合比选,进而确定合适的交通组织方式。研究成果为类似项目的方案分析与选择等提供了技术支持及实践依据。

For the main roads passing through the downtown area of cities, intensively and properly handling the relationship between the transit traffic and the traffic in the area is related to the efficiency of the traffic conversion of the entire passage, and the choice of the traffic organization mode is often determined by the urban landscape, the coordination with the surrounding environment, the synergy with master planning, and project cost etc. In this paper, under the specific control factors of Xiamen Xiang’an Bridge on main island, i.e. the Fangzhong Road, a comprehensive comparisons are conducted in terms of long tunnels, short tunnels and viaducts through multiple factors, so as to determine the appropriate traffic organization mode. The research results provide technical support and practical basis for the scheme analysis and selection of similar projects.
