Qinghai-Tibet railway,the first highland railway crossing permafrost region in the world,was confronted with main three mainly difficult problems,permafrost,high-cold and oxygen deficit,and ecologic frangibility.Its construction was more complicated and difficult than the other permafrost engineering at China and abroad.Due to the nature and complexity during Qinghai-Tibet railway construction,many effective measures were adopted in design and construction including various measures for permafrost protection,measures for labor health and labor protection on plateau,measures for ecological environment protection and preventing pollution,etc.These various measures showed approved effects during railway construction and operation.
