摘要:
国内一些特大城市部分早期开通运营的城市轨道交通线路客流增长迅猛，客流需求远超原设计的线路运输能力，提高其运输能力、缓解运营压力已迫在眉睫。以西安地铁2号线为例，提出增加列车开行密度、压缩行车间隔的扩能方案；并对控制列车运输能力的折返能力、场段规模、供电容量、区间风井的设置等主要因素进行了系统研究。根据方案检算结果，2号线行车密度为33对/h时，工程改造量较低、投资较小，且运输能力可比原设计提高10%，具有一定的抗风险能力。
Abstracts:
Urban rail transit lines launched at early phases in some major cities in China are seeing drastic growth of passenger flow. Passenger flow demand has far exceeded the originally designed line transport capacity. To improve the transport capacity and to ease operational pressure is imminent. Taking Xi′an Metro Line 2 as an example, the capacity expansion scheme of increasing train frequency and compressing operation interval is proposed, and a systematic study of the main factors controlling train transport capacity, including return capacity, scale of depot, power supply capacity, setting of the interval wind well, is carried out. The scheme examination calculation results show that when train frequency is 33 pairs/h, the reconstruction volume and investment are lower, while transport capacity can improve by 10%, equipped with certain level of anti-risk ability.
