漳州开发区双鱼岛旅游铁路建设方案研究

A Study on Construction Scheme of Shangyu Island Tourism Railway in Zhangzhou Development Zone

新建漳州开发区双鱼岛旅游铁路位于福建省漳州市境内,其功能定位为双鱼岛旅游项目配套工程。新建铁路线路同时穿过海域段和海积平原,项目环境敏感点众多、建设条件复杂、施工风险高、难度大。本文结合漳州开发区城市规划、周围环境敏感点、厦门湾地形、地质等因素,从轨道交通模式的选择、区域内线路走向及站点布置、厦漳海底隧道实施难易程度等对双鱼岛旅游铁路建设方案进行综合分析。研究结果表明:(1)双鱼岛旅游铁路宜采用市域铁路模式;(2)推荐滨海新城站至双鱼岛站段线路方案采用沿南滨大道方案,线路沿滨海大道布置滨海新城、厦门大学分校、双鱼岛3座车站;(3)建议厦漳海底隧道位于花岗岩强风化层顶部,优先选择钻爆法施工。

Newly-built Shuangyu Island Tourism Railway in Zhangzhou Development Zone,Zhangzhou City,Fujian Province,a supporting work of Shuangyu Island Tourism Project,runs through the sea area and the marine plain,and is characterized by numerous environmental sensitive points,complex construction conditions,high construction risks,and great difficulties.Combining with the urban planning of Zhangzhou Development Zone,sensitive surrounding environment,topography and geology of Xiamen Bay,and other factors,this paper made a comprehensive analysis on the construction scheme of Shuangyu Island Tourism Railway,including selection of rail transit mode,the route direction and station layout in the region,and the implementation difficulty of Xiamen-Zhangzhou Subsea Tunnel.The results show that:(1)Shuangyu Island Tourism Railway should be constructed as an intracity railway;(2)The scheme along Nanbin Avenue is recommended for the section from Binhai New Town Station to Shuangyu Island Station,and three stations are proposed,namely Binhai New Town,Xiamen University Branch and Shuangyu Island;(3)It is suggested that Xiamen-Zhangzhou Subsea Tunnel should be located at the top of strongly weathered granite layer,and drilling and blasting method should be preferred for construction.
