The Research On The Winter Daytime Skylight Of Harbin Dalian High-speed Railway

Harbin Dalian high speed railway special winter cold weather, At night, the opening of the skylight maintenance personnel and maintenance equipment, there is a certain loss, Increasing the amount of maintenance tasks, increasing the difficulty of maintenance, And with the high-speed railway in our country evening to morning train operation, night driving and maintenance skylight contradict each other.Therefore, it is necessary to study of Harbin Dalian high speed railway in winter day skylight.Harbin Dalian high-speed railway opened a total of 87 pairs of trains, Which mainly in the middle or long distance trains, Through the analysis of the daytime passenger flow,Analysis of daily fluctuation of passenger flow, The law of daily fluctuation of the passenger flow is obtained. The peak passenger flow periods were7:00-8:00 and 14:00-15:00. In accordance with previous traffic volume forecast of Harbin Dalian high-speed railway overnight trains traffic of 4,080 people / day /check. According to both the workload and the time of the night time analysis of the skylight to be provided by the day of the integrated maintenance of the skylight to 3 h,check the roof to 1.5 h, Through analyzing the advantages and disadvantages of various types of skylight, It is found that the sub rectangular skylight is suitable for Harbin Dalian high-speed railway opened day skylight.On the basis of considering the ratio of the stop and the stop station, the calculation of different types of skylight is calculated, Impact by combining different types of skylight and the deduction ratio that segmenting rectangle skylight, the most suitable for daytime Harbin Dalian high speed railway opened. In order to establish the model of the effect of the opening time period on the daytime traffic capacity of the segmented rectangular skylight, Come to Harbin Dalian high speed railway train day skylight scheme, through to the affected train improved to daytime skylight is the basis of driving scheme, Which reduce 7 pairs of train train during the day, night an additional 12 on the evening to morning lie train.The daily operation plan of the above winter, respectively, from the motor car group to use the cost, the economic point of view of the passenger flow to the day of the opening of the adaptability analysis, For additional overnight train pneumatic horizontal the train plan marginal revenue increase value is about 5.9 billion yuan /year.
