LanHe Railway Main Technical Standard And Key Line Selection And Location

Lanzhou to HeZuo railway as a component of the planned Lanzhou to Chengdu railway,the Lanzhou HeZuo railway has been put forward in the early days of the founding of the people’s Republic of china.In 2016,the national development and Reform Commission issued the "long-term railway network planning",clearly in the planning of Lanzhou to HeZuo line,Xining line,HeZuo to Chenjiu ect.nine railway lines,as an important part of "Eight vertical and eight horizontal" regional trunk railway lines,forming a transport channel connected to the northwest,southwest and the Pearl River Delta region railway.Lanzhou to HeZuo railway is located in Gansu Province,Lanzhou City,Linxia Hui Autonomous Prefecture and Gannan Tibetan Autonomous Prefecture,is an important part of Lanzhou to Chengdu railway project,to fill the gaps in railway network in southern Gansu minority areas,expand the railway network coverage.The area along the project is located in the southern part of Gansu Province,located in the transition zone between the Loess Plateau and the Tibetan plateau.Taking Lanzhou to He Zuo railway as an example,this paper studies the main railway line scheme,mainly carried out three aspects of research..(1)Through the analysis of the present situation and development of LAN railway attract within the administrative division,population,industry and agriculture,transportation,combined with the project positioning in the road network,the local traffic flow prediction line and through traffic and passenger traffic,the project cargo and passenger train number.Combining with the significance and function of the line in national economy and road network,the paper analyzes the demand,construction necessity and construction opportunity of the project.(2)Based on the passenger and cargo traffic volume,combined with the main technical standards of adjacent railway lines and the geographical environment in which this line is located,the restricted slope of this line is determined through the analysis and study of the transport organization analysis,economic technology and project implementation difficulty.Combined with transportation characteristics and external power supply,the main technical standards suitable for Lanzhou to HeZuo railway are put forward.(3)Because of the important economic stronghold by the line,the choice of position control toward the circuit scheme,so combined with the line of passenger and freight traffic and the main technical standards,the key research of this scheme is line line passing through Yongjing County,Linxia and HeZuo three county-level city.The geological condition,fault condition and geological structure of the line are complex,and the location of the bad geological section such as fault and landslide is studied.Through the comprehensive analysis and comparison of the route scheme,the construction scheme of the key line of Lanzhou to HeZuo railway is put forward.
