既有铁路增设车站方案可行性:以三亚至乐东铁路为例

Feasibility Study on the Scheme of Adding Stations to Existing Railway:Sanya-Ledong Railway as an Example

利用既有铁路增设车站既可满足城市发展对轨道交通的强烈需求,并能解决新建轨道交通与城市土地资源紧缺的矛盾。本文以三亚至乐东铁路为例,针对利用既有铁路增设车站存在的主要问题,从既有铁路增设车站方案的合规性和施工组织方案两个方面进行分析,通过采取优化信号机布置、增设安全线、进行路基刚性处理和优化施工组织方案等相关技术措施,提出既有铁路增设车站的可行性方案。本文解决了既有铁路增设车站的合规性问题,有效保障了施工和运营安全,也可为类似既有铁路增设车站提供一定的指导及参考。

Adding stations to existing railways can not only meet the high demand for urban rail transit but also solve the conflict between new rail transit and the scarcity of urban land resources.For the main problems of using existing railways to add stations,this article focuses on analyzing the feasibility of adding stations on existing railways,using the Sanya to Ledong Railway as an example to,and considers two key aspects:compliance and construction organization plan,through the adoption of relevant technical measures,such as optimizing the layout of signal machines,adding safety lines,treating roadbed rigidity,and optimizing construction organization plans.This article solves the compliance issue of adding stations on existing railways,effectively ensuring construction and operational safety,and can provide useful guidance for similar schemes of adding stations on existing railways.
