摘要
研究目的:城轨交通线路中的辅助线与正线连接传统方式是采用单开道岔。如能在城轨交通轨道工程设计中使用对称道岔或三开道岔,可达到大幅度节省轨道工程投资之目的。研究方法:通过搜集调查了解我国各大城市的城轨交通辅助性配线形式及运营状况,分析对比对称道岔、三开道岔与单开道岔在结构特征及功能等方面的差别,并研究停车线、出入线在与正线连接时采用对称道岔和三开道岔时合理的平面布置。研究结果:在城轨交通轨道工程设计中采用对称道岔和三开道岔来替代单开道岔,可减少工程数量,降低造价,提高调车作业效率。研究结论:对称道岔和三开道岔在停车线和出入线上使用,是可行的、必要的,并应结合城轨交通建设工程抓紧研制、铺设。
Research purposes： The simple turnout is adopted in the traditional way of connecting auxiliary line with main line in urban rail transit. If symmetrical turnout or three - way turnout can be adopted in urban rail transmit, by which the construction investment can be reduced largely. Research methods： Based on the investigation of arrangement types of and operation status of auxiliary line in urban rail transit in China, the analysis and comparison are made for the differences among symmetrical turnout, three -way turnout and simple turnout. In addition, the research is made on the reasonable plane arrangements of symmetrical turnout and three -way turnout when stabling siding and inbound -outbound siding are connected with main line. Research results： If symmetrical turnout or three -way turnout is adopted to replace simple turnout in urban rail transmit, by which the amount of construction work and construction cost can be reduced and the efficiency of train shunting operation can be improved. Research conclusions： The research shows that it is feasible and necessary to adopt the symmetrical turnout or three -way turnout for stabling siding and inbound - outbound siding. Moreover, the related research work should be done and the turnouts should be produced urgently in combination with the process of construction of urban rail transmit.
