厦门轨道交通5号线过海区间下穿珍稀海洋物种国家级自然保护区线路方案比选研究

Research on Comparison and Selection of Route Schemes for Xiamen Rail Transit Line 5 Cross-sea Section Undercrossing Rare Marine Species National Nature Reserve

下穿珍稀海洋物种国家级自然保护区与跨海段工程一直是厦门城市轨道交通综合选线工作的重要控制点,该段选线工作在考虑环境影响评价、工程风险与投资成本等因素的同时,也须统筹考虑轨道与城市规划、片区开发和客流量吸引等情况。文章对厦门轨道交通5号线跨海段线路方案进行综合比选,旨在为类似工程方案比选提供参考。

Undercrossing rare marine species national nature reserve and the cross-sea section engineering have always been the important control points for the comprehensive route selection of urban rail transit in Xiamen.While considering the factors such as environmental impact assessment,engineering risk and investment cost,the route selection of this section must also consider the situation of rail and urban planning,area development and passenger flow attraction.This paper makes a comprehensive comparison and selection of the cross-sea section on Xiamen Rail Transit Line 5,aiming to provide reference for the comparison and selection of similar engineering schemes.
