| Qinghai-Tibet Railway about 1956km , started from Xining, the capital of Qinghai province, ended at Lhasa, the capital of Tibet Municipality, is an trunk line from the backland of our country to the South-west national border. The construction of Qinghai-Tibet Railway is very important to the perfection of the west railway network framework, to the improve of the economic development of the two districts, to the harmonization of the relationship between the Han nationality and the minority nationalities and the stabilization of the national defence of the South-west part as well as the entire country. The section of the Xining-Golmud, about 815km, has completed in 1979 and put into operation in 1984, is the highest railway in our existing railways. The section of the Golmud-Lhasa started in 2001, is anticipated going into operation in 2006. Due to the special geographic and the vile climate conditions of Qinghai-Tibet plateau, it is very important to research the mode of Qinghai-Tibet railway operation, maintenance and the safety measures adapted to the special conditions.So this paper, based on the status of existing operation of the Xining Sub-administration of Lanzhou Railway Administration, Jining-Tongliao Railway located in Inner Mongolia Municipality and Daxian-Chengdu Railway located in Sichuan province, also taked the railway reform and development into account, consulted the mode of mechanized maintenance in Shenyang Railway Administration and Shanghai Railway Administration, by using both of qualitative analysis and quantitative analysis method of systems engineering theory, analyzes the organization setup, the configure of personnel and equipment, the mode of operation and maintenance and its development after the Qinghai-Tibet railway has been put into operation.The paper suggests that the new organization setup andadministration mode should be adopted. The section of the Golmud-Lhasa should be adopted at the beginning of operation firstly; the section of Xining-Golmud and the section of Golmud- Sinkiang which is in the long-term programming should be followed gradually. The Qinghai-Tibet Railway Corporation, according to the principle of detaching service companies from operations, separating the railway infrastructure and operations, is composed of Railway Infrastructure Corporation, Mobile Equipment Corporation, Passenger and Cargo Transportation Corporation, Traffic Control Center and Service Companies. The Railway Infrastructure Corporation, responsible for the fixed facility maintenance and operation which include buildings and structures maintenance, water and electricity supply, signal repair and track maintenance, is composed of Mechanized Track Maintenance Corporation and Synthetic Maintenance Corporation. The Mechanized Track Maintenance Corporation is in charge of track geometry measure, rail flaw detection, mechanized comprehensive track maintenance and track medium maintenance. The Synthetic Maintenance Corporation on the principle of "one job with multi-duty" and reducing the fixed number of employees and departments, is in charge of regular maintenance of track, signal, bridge, buildings and tunnel structures, intermediate and overhaul repair of signal, buildings and structures, supply of water and electricity. While the major repair of track, roadbed, bridge and tunnel structures are not calculated. Whenever major repair is needed, to invite public bidding is a good idea.Along with all of the aforementioned measures, the target of reducing the fixed number of employees and departments, enhancing productivity and efficiency, assuring safety and reducing labor intensity, should be realized.In this paper, AHP (Analytic Hierarchy Process) method also be used to analysis and appraise the mode of mechanized track maintenance. The conclusion reflects that the mainframe-machine and mid-machine should be adopted in the section of the Golmud-Lhasa, minitype machineshould be used as added equipment in the section of Xining-Golmud in order to complement the capabili... |
