连镇铁路接轨沪宁城际铁路丹徒站方案研究

Lianzhen Railway Connecting with Dantu Station on Shanghai-Nanjing Intercity Railway

连镇铁路为客运专线,设计速度为250 km/h,为有砟轨道线路。沪宁城际铁路设计速度为300 km/h,为无砟轨道线路。连镇铁路在丹徒站接轨沪宁城际铁路。由于丹徒站未预留接轨条件,因此接轨方案十分复杂。结合运输需求,通过方案比选,选用了合理的接轨布置方案;结合列车控制技术要求,通过调整信号设备布置,改造后的丹徒站可满足单方向进路16节编组动车的停靠要求;通过采用合理的技术方案和施工措施,施工期间可以满足沪宁城际的正常运营的要求。该接轨案例在国内十分罕见,除了土建工程外,“四电”工程迁改及过渡也非常复杂。

Lianyungang-Zhenjiang High-speed Railway(abbreviated as Lianzhen Railway)is a passenger dedicated line with a design speed of 250 km/h,and is a ballasted track line.Shanghai-Nanjing Intercity Railway is a ballastless track,the design speed of which is 300 km/h.At Dantu station,Lianzhen railway is connected with Shanghai-Nanjing Intercity Railway.Since no connection conditions are reserved at Dantu Station,the connection scheme is very complex,but through comparison and selection,a reasonable connection layout scheme is selected.Then,combined with the transportation demands,and considering the technical requirements of train control,signal equipment layout is adjusted,the reconstructed Dantu Station can meet the parking requirements of 16 EMU train formation on the single direction route.And by adopting reasonable technical scheme and construction measures,the normal operation requirements of Shanghai-Nanjing Intercity Railway can be met during the construction period.The connection case studied in this paper is very rare in China,in addition to civil engineering,the relocation and transition of communication engineering,signal engineering,power engineering and electrification engineering are also very complicated.
