Research On Transport Organization Of The Plateau Railway From Lhasa To Rikaze

Lari Railway, from the capital of the Tibet Autonomous Region Lhasa to Rikaze which is the ancient city of the Panchen Lama, is located in the roof of the world which is known for its complex geological conditions and harsh climates. As an extension of the Qinghai-Tibet railway line, it is an integral part of the main skeleton of the "T"-shaped railway network in Tibet Autonomous Region, leading to the railway of South Asia, and it will play an important role in the regional road network.But in addition to its location in the alpine and hypoxia area, Lari Railway also has the feature of small quantity of passenger and freight traffic, which has the seasonal and unbalanced nature. Thus this paper approaches the railway transportation organization of characteristics of plateau, based on the politics, economy, geography and culture in Tibet. This paper includes following parts:1. Based on the Lari Railway attracted area's political, geographical, economic status as well as its construction programs, it researches the main technical standards, the distribution of main railway station and the design of switching station status of Lari Railway.2. It calculates the operating logarithm of the passenger train from Xining via Lhasa to Rikaze by MOLP. And on the ground of the characteristic of seasonality for Lari Raiway, it devises the operation of passenger train by low and busy season of passenger capacity.3. Considering the condition of time difference in the plateau, it uses the congruence theory to approach the reasonable extent of operation under the circumstance of passenger station along the railway, reentry, and other factors.4. Given the job content of synthesis maintenance time, combined with natural environment of high altitude and coldness, it analyses the mechanization of maintenance operation for Lari Railway, and further calculates the time appropriate for its synthesis maintenance time by the analysis on the efficiency of large maintenance machinery. It approaches how to design the synthesis maintenance time by considering the working hours, the principle for synthesis maintenance time and requests for train working in the plateau. Thus it gives some suggestive opinions for the safety control of synthesis maintenance time, targeting on the work characteristic in the plateau with its harsh environment.5. It analyses the hash climate condition and severe geography in plateau, and on this ground it forms some measures that could be taken for transportation of Lari Railway under the circumstance of easy sand wind, snow damage, frost, landslide and earthquake.
