摘要/Abstract

摘要： 青藏铁路是世界上第一条跨越高原多年冻土区的铁路，工程建设环境面临多年冻土、高寒缺氧、生态脆弱的“三大难题”，比国内外其他多年冻土工程建设更艰巨和困难。由于青藏铁路建设环境的特殊性与复杂性，设计和建设中采取了多种保护冻土的有效措施、高原劳动卫生和劳动保护措施及生态环境保护措施及污染防治措施，各项措施在青藏铁路的建设和运营中显示出了良好的效果。

关键词: 青藏铁路, 多年冻土, 高寒缺氧, 环境保护

Abstract: 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.

Key words: Qinghai-Tibet railway, permafrost, high-cold and oxygen deficit, environment protection
