The Research Of Heavy-loaded Transportation And Related Issues

The railway as the important infrastructure of the national economy and the powerful measure of national magnificent regulation is very important in transportation system. And with the development of the national economy , the conflicts that the capacity of railway can't satisfy the transport quantity demand becomes much more serious . In the background that the competition of transport market is much more fierce day by day , we need advance the sending capacity of the railway line imperatively based on the existent fixture .There are three ways to advance the railway line capacity .The first way is improving the vehicle load .The second and third way is increasing the traveling density and increase the traveling speed. It is clear in our county that the traveling density of the railway is very high in the world and it is hard to increase the traveling speed now compared with the huge potentiality of vehicle load . Based on these points, improving vehicle load is the most effective measure to advance railway line capacity , and it is also an important resort to improve the indexes of the railway operation to depress the transport cost.The traveling organization is the hard core in the heavy load transportation of the railway. And the research on the traveling organization of heavy load transportation is very significative to the development of railway .According to the summarization of the development of railway heavy load transportation abroad ,the paper tries to analyses the traveling organization of heavy load transportation by the numbers combined with the development of heavy load transportation in our county.First ,the research on the advantage of direct and unit heavy load train is carried out in the paper through the qualitative and quantitative analysis . Simultaneously , the paper analysis situation of the Da-qin railway transportation organization based on theory forenamed .Further more , based on this background ,the estimation of development foreground ,the sale and level of Da-qin railway according in the method of cubic exponential smoothing method . Then the analysis and estimation of the forecasting is given for the capacity expand of heavy load transportation of Da-qin railway.The dissertation gives the research on the mode of Da-qin railwaytransportation organization and seeks the rational operational projects by the linear programming model .Based on these analysis, the resolving of Da-qin railway operation raised which is very significative to the extend and development of heavy load transportation .The research results of the dissertation can be used in the development of heavy load transportation in our country as the reference.
