Study On Railway Line Location Design Of The Newly-built Tahanjiacun-Tarangaole Mining Area Railway

The implementation of reconstructing Tahan line will improve the transportation network in the western inner Mongolian,greatly improve the transportation capacity,accelerate the adjustment of the industrial structure,promote the optimization of the distribution of the productive forces,realize the coordinated development of the regional economy,change the advantage of the resources to the economic advantage,speed up the pace of the rich in the poor areas of the poor and old and the young,and effectively improve the living standard of the people.At the same time,it is of great significance to ensure the national energy supply and transport safety,carry out the "western development" and the overall development strategy of building a well-off society in an all-round way.An in-depth analysis on the line selection according to reconstructing the Tahan line design problems,the main work and conclusion are as follows1.The reconstruction analysis of transportation of Tahan line.This paper mainly includes the analysis of the social and economic characteristics for the scope of attraction and the analysis of transport demand.The analysis of social economic characteristics mainly includes the determination of the scope of attraction,the analysis of social economic characteristics,and the current situation of transportation.And then analyze the transport demand of the Tahan line,on the basis of the volume and flow of the whole line,it gives the traffic volume along the near and forward lines along the line as well as the transport volume of the main station goods.Finally,the area cargo density is given.2.The reconstruction of Tahan line's engineering characteristics analysis.This paper mainly includes the analysis of natural characteristics,technical characteristics and main technical standards of lines.The analysis of natural characteristics includes topography,climate,geological structure,hydrogeology,and engineering geology and so on.The analysis of line technical features mainly includes the railway grade,the number of positive lines,the limit slope,the minimum radius of the curve,the type of traction,the type of locomotive,the quality of traction,the effective length of the hair line and the type of block.At last it introduces the main technical standards about the new line and the railway which is adjacent to Tahan.3.The analysis of line selection scheme in three sections about the reconstruction of Tahan line.This paper aims at the three key sections of the line,which prefers to the whole line plan,Wu Jiaqu partial plan and GDK10+800-GDK15+000 section plan.According to these,Putting forward the different route selection schemes for each section,analyze the engineering characteristics of each plan in detail,and the same time analyze the economic and technological factors.4.The scheme comparison of reconstructing the Tahan line.The application scope and modeling steps of the grey relational decision-making theory for the following three sections which are selected for the optimization of the line selection.For the whole line plan,Wu Jiaqu partial plane plan and GDK10+800-GDK15+000 segment plan,respectively.According to the evaluation of the calculation steps of grey relational decision making,the optimal line selection scheme is selected.First,the original data is determined,and then the original data is standardized.Finally,the Matlab algorithm is designed to solve the problem.Finally,we get the overall scheme of the transmission line.We adopt the CK plan and Wu Jiaqu partial plan plan,and adopt the CK plan and GDK10+800-GDK15+000 segment plan to adopt the final result of the B plan.
