Description
Technical field
The present invention relates to railway transport field, relate in particular to a kind of computing method and system of transfinite lorry and adjacent line passenger train meeting following distance.
Background technology
Railway over-limited goods means that physical dimension is huge, needs the big goods in space in transit.Its freight volume portion in the total freight volume of railway goods is little, but mostly is the visual plant that modernization of the country is built, and therefore, the off-gauge goods transportation has vital role to development and national economy.
Along with developing rapidly and the continuous expansion of foreign trade of Chinese national economy, the transportation demand of railway over-limited goods also increases day by day, off-gauge goods transportation and national economy, national defense construction concern closer, therefore safety, rapidly, economical, transport off-gauge goods expediently, remain a crucial task of transportation by railroad.Since nineteen ninety-seven, China railways has been carried out raising speed by a large scale continuously five times, the passenger train travelling speed has realized historic leap, and rapid line extension mileage reaches 1.65 ten thousand kilometers, and the passenger train travelling speed reaches 160km/h and above circuit extension mileage reaches 7700km.Main lines with good conditionsi such as that the Ministry of Railways plans is wide at Beijing-Harbin, Beijing-Shanghai, capital in 2006, Long Hai, Lanzhou and Xinjiang, glue Ji, military nine, Jiangxi, Zhejiang are implemented the 6th speed-raising, speed-raising passenger vehicle highest running speed will reach 200km/h, behind the 6th raising speed by a large scale of china railway, allow travelling speed to reach the above circuit extension mileage of 120km/h and will reach 2.2 ten thousand kilometers.In order to improve railway transport capacity, the lorry speed of raising speed railway and passenger vehicle speed are complementary, goods train speed will be brought up to 120km/h by present not enough 80km/h.This transportation to railway over-limited goods is had higher requirement.
The off-gauge goods profile is huge and heavy, and the space that needs in transit is big, the vehicle that off-gauge goods is housed by way of buildings along the line or equipment the time, often need to limit travelling speed in addition stop after restart go slowly by; On the multiple line circuit, often need speed limit during with the adjacent line train crossing, even forbid meeting.Thereby the ability of off-gauge goods transportation busy line is many, normal running order is disturbed big.Especially the travelling speed of other train is high more, and the train running speed that hangs with the lorry that transfinites is low more, and then the off-gauge goods transportation is many more to taking of line capacity.In order to reduce the interference of off-gauge goods transportation as far as possible to normal running order, adapt to the requirement of passenger and freight train raising speed by a large scale, utilize the China railways gauge economically, further improve the transportation of China railways off-gauge goods and organize level just to become the task of top priority.
With regard to present achievement in research, the China railways lorry meeting condition that transfinites, beginning sees the nineteen fifty-two Ministry of Railways " the exceptional dimension freight shipment provisional rule " announced with iron driving skills (52) the 35 command, and this rule is to use for reference external relevant regulations and formulate in conjunction with the actual conditions of China railways at that time.Owing to lack the practical experience of China oneself, so there are many imperfection parts in this rule.Over more than 50 year, China railways line standard improves again and again, the performance of lorry is constantly improved, the off-gauge goods transportation has also had very great development, " railway over-limited freight transportation rule " (existing is " railway over-limited dead weight cargo transportation rule ", hereinafter to be referred as " super rule ") also carried out repeatedly revising, but owing to many reasons, the basic theory and the still deep research of shortage system of technical conditions of off-gauge goods transportation, cause in " super rule " relevant railway over-limited lorry meeting condition etc. not become substantially all the time, seriously break away from current China Railway reality.
China railways constantly raises speed at present, the train speed large tracts of land, increase substantially, the passenger train top speed has been carried to 200km/h, the goods train highest running speed will be carried to 120km/h, railway over-limited goods train meeting technical conditions under new technical equipment behind the train speed raising and the transportation organization condition will change a lot, if in time do not adjust off-gauge goods train and passenger train meeting technical conditions, then there is certain potential safety hazard according to the variation of train operation condition.
