朔黄重载铁路局部区段扩能改造方案研究

随着朔黄铁路运量的逐年攀升,下行线谭家庄线路所—肃宁北站区间通过能力不足的问题日益凸显,亟待进行扩能改造.本文基于既有线路的实际运行情况,对改建王佐下联线、改建朔黄铁路下行线两种线路走向方案进行了对比分析,确定采用改建王佐下联线方案,并对该方案控制性工程特大桥上跨京九铁路、肃宁上联线的4种桥型方案进行了比选,选定采用主...

Study on Capacity Expansion and Reconstruction Scheme of Local Sections of Shuozhou-Huanghuagang Heavy Haul Railway

With the increasing traffic volume of Shuozhou-Huanghuagang railway year by year,the problem of insufficient carrying capacity between Tanjiazhuang block house and Suning north station on the down line is becoming increasingly prominent,and capacity expansion and reconstruction are urgently needed.Based on the actual operation of the existing railway,the two route alignment schemes of reconstructing Wangzuo down connecting line and reconstructing Shuohuang railway down line were compared and analyzed,the scheme of reconstructing Wangzuo down connecting line was determined.The comparison and selection of four bridge type schemes of super large bridge crossing Beijing-Kowloon Railway and Suning up connecting line in the control project were carried out,and the low tower cablestayed bridge with main span of(60+110+60)m was selected.The near and far future traffic volume of ShuozhouHuanghuagang railway is predicted.After the reconstruction of this section is completed according to the above scheme,the section carrying capacity can meet the transportation capacity growth demand of Shuozhou-Huanghuagang railway.
