摘要
南京地铁2号线东延线工程在国内首次应用了鱼腹形岛式站台设计,目前已经建成运营3年,取得了良好的效果。阐述该站型所具有的技术优势,包括缩短区间喇叭口过渡段长度、提高车站景观效果、优化车站站位、降低工程投资、改善线路线形等。针对该站型设计所面临的问题,如线路曲线参数的选择、站台宽度的确定、楼扶梯布局,以及运营中可能出现的站台门夹人、站台缝隙较大致使乘客陷脚等问题,提出可行的解决方法及关键性的设计思路,给出其技术参数,为该站型的推广应用和设计实践提供借鉴和指导。
The East Extension Line project of Nanjing Metro Line 2 is the first to adopt fish-belly island platform design in China. It has obtained favorable results since it was put into operation 3 years ago. This paper elaborates the technological advantages of this de- sign, such as shortening transition section length of the bell mouth, improving visual effect of the station, optimizing its location, reduc- ing project investment, and improving the alignment of lines. This paper also proposes feasible solutions to the critical points and difficulties in the platform design, such as the parameter choice of the curve lines, the breadth of the platform, the layout of escalators, as well as the problems that passengers are nipped by the door of the platform or the big gap between the platform and the ground. This paper will provide references and guidance for the extensive application and design practice of such station type.
