摘　　要：研究目的:对于有地下线路的铁路工程,由于开挖土方等方面的问题,要求站坪长度尽量缩短,以节省工程投资。现有CTCS-2+ATO列控系统因其安全防护距离设置位置、车载设备安装位置、适应的运行速度较高等原因,对站坪长度要求较CBTC列控系统长,成为在市域铁路运用时的不利因素,需要对其进行短站坪长度需求的适应性分析并提出适宜的解决方法,提升系统的竞争力。研究结论:(1)侧线股道增设安全线,基于列车停稳信息及时解锁过走防护区段、利用应答器报文增加过走防护区段信息、及时回缩列控移动授权范围等配套方法,将安全距离、附加距离设于目标点信号机的内方,利用安全线及咽喉区线路缩短股道区线路长度;(2)合理约束车载应答器接收天线安装位置,根据市域列车运行速度计算、确定可靠解析出报文所需要的应答器距离信号机距离,以及应答器组间最小距离要求,最终确定股道出站应答器安装位置最小长度需求;(3)经折返线道岔侧向的进路不发低频码,轨道电路长度仅考虑轨道占用检查时间,进一步缩短折返道岔区段长度要求;(4)本研究成果在市域铁路中有广阔的运用前景。Research purposes:As for the railway project with underground sections,because of the earth excavation,it is required that the length of station site is as short as possible in order to save the investment.Because of the setting position of the safety protection distance,installing position of the on-board equipment,adaptability to the higher speed,the station site length requirement of the existing CTCS-2+ATO system is larger than that of the CBTC system.The disadvantage is shown while using in suburban railway.It is needed to analyze the CTCS-2+ATO system adaptability to the shorter station site length,put forward the suitable method and improve its competitiveness.Research conclusions:(1)Adding safety line to the siding track,based on unlocking the overlap section in time using standstill message and adding overlap section message to the balise telegram in order to draw back the MA in time,setting the safety protection and additional distance inside the signal,using the section of safety line or throat section to short the length thesiding track;(2)Reasonable restricting the installing position of on-board balise antenna,calculating the distance between the balise and the signal and the distance between the balises in the balise group according to the speed of the suburban railway while ensuring the reliable telegram interpreting,and then defining the shortest length requirement of the balise installing in the siding track;(3)No-coding to the turn-back route through turnout branch,the length of the track circuit meeting the requirement of the track occupancy check only in order to shorten the length of the turn-back line switch section;(4)The research findings can be widely used in the suburban railway.
