Analysis Of Transportation Capacity And Design Of Improvement And Reconstruction Plan Of Jiusumu-Yanzhuang Section In The Dazhun Railway

Dazhun-Daqin Passage is the path with the lowest price and shortest distance of coal transportation in Western Mongolia,which has great market competitiveness.The transportation capacity of the upper and lower passages of Dazhun railway is far greater than that of the single-line section of Dazhun railway.Therefore,the Jiusumu-Yanzhuang single-line section of Dazhun railway has become a restricted section for coal transportation in Dazhun-Daqin passage.The main problems and weaknesses are the shortage of transportation capacity and the low quality of transport,and thus improving the passing capacity of the railway from Jiusumu to Yanzhuang section has become an urgent problem.Firstly,the paper summarizes the achievements of theoretical research on railway transport capacity enhancement at home and abroad,introduces the theoretical basis of railway transport capacity enhancement,and summarizes the main methods and measures of railway transport capacity enhancement.On this basis,the paper analyses and introduces the basic conditions of the existing transport equipment and the specific conditions of the actual transport organization and production in the Jiusumu-Yanzhuang single-track section of Dazhun railway,calculates the transport capacity of the Jiusumu-Yanzhuang section of Dazhun railway under the existing transport conditions by means of analysis and calculation,and puts forward the Jiusumu-Yanzhuang section of Dazhuan The transport capacity of the single line section can not meet the near future transport demand.On the basis of in-depth analysis of the existing problems in Jiusumu-Yanzhuang section of Dazhun railway,a series of schemes are put forward to upgrade and reform the transport capacity of the relevant stations,lines,locomotives and rolling stock,and to strengthen the transport organization.At the same time,after calculating the transport capacity of these schemes,it is found that the long-term transport demand of Jiusumu-Yanzhuang section of Dazhun railway can not be satisfied.Finally,the plan of adding the second line is put forward,and the transport capacity improved after the implementation of the plan is analyzed and demonstrated.Compared with the short-term and long-term transport demand,the comparison results show that the construction of the second line can effectively improve the railway transport capacity of Jiusumu-Yanzhuang section and meet its short-term and long-term transport demand.This paper puts forward a plan to improve the railway transport capacity from Jiusumu to Yanzhuang,which is in line with the current situation of the single-track section of Dazhun railway from Jiusumu to Yanzhuang,and can be used for reference in other similar sections to enhance the railway transport capacity.
