Abstract:Research purposes: As stipulated in‘Computer Interlocking System Technical Conditions(TB/T 3027- 2002),a successive route should be provided at the end of vehicle access route for the station with a down grade of 6‰ converted within the braking distance outside the home signal. When there is catch siding or separation facility at the end of an access route,the successive route should be set towards and linked to the siding or the facility; If there is not, to the main track instead. In China, there are some stations with a down grade of 6‰ converted within the braking distance outside the home signal. According to the regulations,the successive route should be provided. As successive routes would have great impacts on the passing capacity of high-speed railway stations,the study about the passing capacity is necessary. This article makes a system analysis on the impacts,which may be caused by providing successive access routes on high-speed railways,upon the arrival-arrival interval,arrival-running through interval,arrival-departure interval and arrival-departure interval of stations.
Research conclusions:(1)Based on the studies,successive routes would have great impacts on the passing capacity of high-speed railway stations and the arrival intervals at stations increase by more than 2.3 min and so do the arrival-running through intervals.(2)Setting catch sidings concurrently is not an effective solution either, so setting catch sidings is not necessary.(3)The research results have a reference for the stations design and the passing capacity analysis of high-speed railway.
