武汉地铁梨园站与华侨城支线换乘方案研究

Study on Transfer Schemes between Liyuan Station and OCT Branch Line of Wuhan Metro

根据规划要求,武汉地铁8号线需引入规划华侨城。华侨城紧临东湖风景区,是8号线主方向的突变点,为解决8号线与华侨城结合换乘的困难,结合梨园站设计实例,通过分析车站周边的控制因素,探讨支线独立运营与共线运营模式下,行车组织是否满足要求,研究叠岛、一岛一侧和双岛3种换乘方案下,车站在规模、换乘功能、造价、区间对东湖风景区的影响、交通疏解及施工风险等方面的优缺点,确定适合本站的换乘方案,使华侨城支线与地铁8号线良好地覆盖了周边区域,有利于区域的快速发展,为地铁主线与支线换乘方案的选择提供参考依据。

According to the planning,No.8 Line of Wuhan Metro should be extended to OCT.As a result,a “Y”-shaped Metro line is designed,with Liyuan station as the transfer station between the main line and the OCT branch line.In this paper,the transfer schemes between Liyuan station and OCT branch line are studied on basis of three station types,i.e,separate-floor island station,one-island and one-side-platform station and two-island station,and by analyzing such factors as the train operation organization mode,the station scale,the transfer efficiency,the construction cost,the influence on Dong Lake scenic area,the traffic evacuation and the construction risk.Conclusion is drawn that the transfer scheme based on one-island and one-side-platform station can meet the requirements of the coverage rate and development of the Metro line.The paper can provide reference for similar projects in the future.
