上海市轨道交通2号线东延伸工程接轨点线路方案研究

The Research on Track-Connecting Point Route Scheme of East Extending Project of Shanghai Rail Transit Line 2

为减少高架区间对现状地块的影响,轨道交通2号线东延伸工程需采用地下形式。既有2号线并没有为东延伸地下接轨预留条件,所以作为延伸工程,接轨点方案便成为本工程的技术难点之一。通过对轨道交通2号线东延伸工程接轨点线路方案的分析研究,从既有地下龙阳路站接出接轨点方案改造工程量太大,从既有龙阳路站至张江高科站区间出岔接出的接轨点方案无法设置平行进路,所以轨道交通2号线东延伸工程只能从龙阳路站至张江高科站地下区间直接接出。

East extending project of Shanghai Rail Transit Line 2 is an extending project which based on existing Rail Transit Line 2. Using underground pattern is required so as to reduce the influence of the elevated interval on the present situation. Since favorable conditions are not preserved for underground connections between the extending line and the existing line 2, as an extending project, the scheme of track-connecting point becomes one of the technical difficulties of this project. According to this paper＇s analysis and research on the route scheme of connecting point of the east extending project of Shanghai Rail Transit Line 2, the alteration work amount could be enormous if we connect from the subway Longyang Road Station and if we connect from the point which is turnout in the interval of existing Longyang Road Station and Zhangjianggaoke Station, the parallel route cannot be set up. Therefore, it is the only method that the East Extending Project of Shanghai Rail Transit Line 2 directly connects the existing line from the underground interval between the Longyang Road Station and the Zhangjianggaoke Station.
