Research On Capacity And Coordination Of High-speed Railway Station

With the continuous construction and development of China’s high-speed railway,taking high-speed railway has brought great travel convenience to people,and has also become the main mode of transportation for people to achieve long-distance travel.Although the increasing number of high-speed railway trains meets the demand of people to choose high-speed railway services,this situation leads to many problems becoming increasingly prominent.The increase of the number of trains will increase a certain pressure on the transportation organization of the station,and the equipment utilization of the station has become a key factor affecting the carrying capacity of the high-speed railway station.Station carrying capacity checking is a scientific method for reasonable evaluation of station transport capacity resources.The calculation of station carrying capacity is an important link in the process of checking,which is of great significance to accurately explore the potential of station transport.The existing theoretical calculation method of high-speed railway station carrying capacity is still in accordance with the traditional calculation theory of common speed railway passenger station,and can not well combine with the characteristics of highspeed railway train in station operation process,so the final results are quite different.Based on the characteristics of high-speed train operation,this paper puts forward a sectional route release interpolation method with occupation time constraint,gives the constraint conditions of occupation time,improves the applicability of interpolation method,and forms a relatively complete calculation method system of carrying capacity.Through the verification of an example,it is found that the sectional route release method can improve the carrying capacity of the station,The calculation results of sectional route release interpolation method can fully reflect the available capacity of the equipment,which is in line with the actual situation of the station.Based on the calculation results of carrying capacity,this paper further explores the static and dynamic coordination problem of high-speed railway station system capacity,constructs the calculation model of static and dynamic coordination degree,and defines the coordination degree value.The calculation model of coordination degree has different parameter value requirements according to different analysis angles,which can better reflect the coordination situation in the calculation results.By combining the analysis results with the actual work situation of the station,the calculation model of coordination degree has a good evaluation effect on the coordination situation of the station capacity.
