| With the running of10,000-ton train on the heavy-loaded railway, the quality of district stations for10,000-ton train working were required more and more higher. Reception-departure tracks were extended to1700s and the middle switch was installed between tracks, which can meet the requirements of receiving and departure of ordinary trains and10000-ton trains.The carrying capacity of district station for10,000-ton train should be calculated when Railway Survey and Design presented the design proposal. So it’s very important to calculate the carrying capacity of district station for10,000-ton train accurately.This paper finds out the method of computation on leisure coefficient of station throat points and leisure coefficient of reception-departure track, though analyzing the difference between district stations for10,000-ton train and ordinary district station. Then the carrying capacity of district station for10,000can be calculated with the leisure coefficient. In this paper, the main research contents include:1. Analyzing the technical features of district station for10,000-ton stationThe technical features of district station for10,000-ton station from the difference between ordinary stations in the effective length of arrival and departure track, the kinds of turnouts and the technical operation was summarized.2. Finding out the method of computation on leisure coefficient of station throat pointsFirstly, the station throat point were grouped. Then the time of occupied directly and the directly obstructived were calculated. The parallel operating table was used to calculate the indirect obstructive time. So that the value of the leisure coefficient of station throat points can be exactly obtained with the analytical calculation method.3. Presented the calculation method on leisure coefficient of reception-departure trackThe leisure time of reception-departure track was related with the numbers of tracks, the number of trains and the kinds of trains, and the technical operation of trains. The computer simulation method was used to calculate the leisure coefficient of reception-departure track with the operational program. Finally, the value of leisure coefficient of reception-departure track can be exactly obtained with the analytical calculation method.4. Calculating the carrying capacity of Zhangzi South district station Zhangzi South district station was one of the district stations in the Shanxi South-Central railway passage. In this paper, leisure coefficient of station throat points and leisure coefficient of reception-departure track were calculated. Finally, the carrying capacity of Zhangzi district station was obtained. |
