青藏铁路站后工程分析

Station Facilities Engineering Analysis of Qinghai-Tibet Ra ilway

分析青藏铁路站后工程在系统方案、设备选型与管理方式等方面的特定要求。论述高海拔站后工程对相关人群的健康生存和正常工作的影响,对牵引动力和工程机械的工作性能的影响,对高低压电器设备的影响,对房屋和给排水工程的影响。认为青藏铁路站后工程设计必须在体现铁路行业共性要求的前提下,顺应和体现该线的个性特征。选定试验段位置应遵循的原则是:有足够的海拔高度,使实地试验能检验海拔4000m～4500m以上的情况。有足够的长度,使站后设备能在相应的系统中动作。亦对站后工程设计的要点,工程设计与科研工作的任务、特点,及其工程试验段的试验内容进行了论述。

The paper analyzes the specific requiremen t of the post-station engineering of Qinghai-Tibet railway in system solution,eq uipment type selection and management mode.It describes the impact of the post- station engineering at high altitude on the living quality and working condition s of the relevant people,the effect on the performance of traction power and con struction machineries,on the electric devices of high and low voltage and on the buildings and water supply and drainage engineering.The paper under the precond ition of meeting the common features of railway industry,shall give way to and e mbody the individual features of the Qinghai-Tibet railway.The principle of sel ecting the test section is: a) sufficient altitude so that the in-situ test sha ll be able to reflect the real condition of 4 000 m—4 500 m above sea level;and b) Long enough section so that the post-station equipment shall be able to ope rate in the corresponding system.The paper also discusses the key points, the e ngineering design,the tasks and the characteristics of the design and research,a nd the test contents.
