摘要
在一定行车条件下,计算不同道岔型号和列车牵引质量对应的列车起停车附加时分、单线铁路运行图周期和双线铁路列车追踪间隔时间,在此基础上计算得到相应条件下重载单、双线铁路车站的通过能力。根据不同道岔型号对车站通过能力影响的分析,对于重载单线铁路车站,在列车牵引质量低于1万t时建议采用9号道岔,当列车牵引质量达到1万t及以上时建议采用12号道岔,仅当列车牵引质量都达到2万t且在场坪条件允许时采用18号道岔;对于重载双线铁路车站,当列车牵引质量在2万t以下时建议采用12号道岔,当列车牵引质量达到2万t且场坪条件允许时建议采用18号道岔。
The starting and stopping additional time, train diagram cycle of single-track railway, and train tracking interval time of double-track railway corresponding to different train traction weight and turnout type are calculated under certain running conditions. On this basis, the station carrying capacity of heavy haul single-track and double-track railway under corresponding conditions is obtained. According to analyzing the impacts of different turnout types on station carrying capacity, the conclusions are drawn as follows. For heavy haul single-track railway station, 9# turnout is recommended when train traction weight is less than 10 000 t; 12# turnout is recommended when train traction weight is equal to or greater than 10 000 t; 18# turnout is recommended only when train traction weight is up to 20 000 t and meanwhile the station site is large enough. For heavy haul double-track railway station, 12# turnout is recommended when train traction weight is less than 20 000 t; 18# turnout is recommended when train traction weight is up to 20 000 t and meanwhile the station site is large enough.
