摘要
以南宁地铁5号线一期工程跨邕江段区间为例,通过行车模拟牵引计算的结果并结合车站方案,得出不设区间风井的临界条件;进一步从工程实施难易度和经济性等方面,分析通过加长车站轮廓缩减区间长度的合理性,进而得出设置该区间风井是必要的,且具有较为合理的选址方案。最后总结出长大区间设置区间风井时需要着重注意的几个方面,为其他线路提供借鉴。
This paper takes the first phase project of crossing under Yong River section on Nanning metro line5as an example.With results of the simulated train running and traction calculation and the station plan scheme,works out the critical conditions for the absence of ventilation shaft in the section.It further analyzes the rationality of the reduction of the section length by expansion of the station profile from the aspect of engineering implementation difficulty and cost-effectiveness,and it leads to the conclusion that it is necessary to set up ventilation shaft in the section and there is a proper site selection.It summarizes that several aspects should be paid attention to when setting up ventilation shaft in a long-distance section,which provides references for other lines when encountering the similar problems.
