地铁既有车站改建中的几个问题

研究目的:解决工程实际问题,对既有线改造中遇到的几个典型问题进行分析。研究方法:通过天津地铁1号线既有线改建工程二纬路站和哈尔滨地铁1号线一期工程烟厂站两个既有车站的改造实例,对既有线改造中的几个问题逐一加以研究论述。研究结论:由2个不同城市既有车站的改造实例可以看出,既有地铁交通线路的改扩建以"利用区间、重建车站"为指导原则进行改造利用。区间隧道内设备管线布置相对简单,易于改造利用。车站直接服务于乘客,也是设备集中的地方,难于改造。重建车站既能提高地铁服务质量,又彻底解决了既有车站技术上的诸多不足。

Several Problems in Reforming Existing Underground Stations

Research purposes:This paper analyzes several typical problems concerning existed routines in order to solve practical engineering problems.Research methods:Through studying of two reforming examples of existing routines regarding Erweilu Station of Tianjin Underground Routine One and Tobacco Factory Station of Period One of Haerbin Underground Routine One,this paper further researches and discusses problems in existing routines one by one.Research conclusions:From the above two different examples of reforming of existing station,we can reform and utilize existed routines based on the guide principle of "utilizing section,reforming stations".Due to the comparatively easy disposal in section tunnel,it is easy to reform.As stations serve passengers directly,in which equipments are gathered together,it is difficult to reform.Rebuilding stations not only can improve underground service quality but also can solve the technical insufficiency of existing station completely.
