南京轨道交通S3线高架鱼腹岛式站台车站的优化设计

Optimum Design of Elevated Fish Belly Platform Station on Nanjing Metro Line S3

鱼腹岛式站台车站在缩短喇叭口长度、塑造城市景观、优化站位方面有着突出的优点,但存在列车平稳性较差、站台间隙过大等问题。通过总结运营经验和不足,基于南京轨道交通S3线工程特点,优化了线路半径、站台宽度及站台间隙等技术参数设计,分析了高架鱼腹岛式站台车站的适应性,为其他类似项目提供借鉴。

The station with fish belly island has outstanding advantages in shortening the trumpet length,shaping the city landscape and optimizing the station location.But there are some problems,such as the poor train smoothness and large platform clearance.By summarizing the experiences and shortcomings in operation,and combined with Nanjing metro Line S3 project,technical parameters like the appropriate line radius,platform width,platform clearance and others are optimized,the adaptability of elevated fish belly island platform is analyze to provide reference for other similar projects.
