青藏铁路多年冻土区路基工程具有海拔高、气压低、空气稀薄、气候严寒、地质条件和水质条件复杂,以及生态环境脆弱等特点,其施工方法不同于一般低海拔非冻土地区路基施工方法。此文根据青藏铁路设计施工科研攻关成果和现场施工经验,对多年冻土区路基路堤、路堑及过渡段路基等工程施工方法进行分析论证,对今后多年冻土区工程建设有一定的参考作用。
Subgrade construction of permafrost region on Qinghai-Tibet Railway is characterized by high altitude, low pressure, thin air, cold climate, complicated geological conditions and water quality, and fragile ecological environment. The construction method is different from subgrade construction methods in non-permafrost areas . Based on the research results of Qinghai-Tibet Railway’s design and construction and on-site construction experience, this paper analyzes and proves the construction methods of embankment embankment, cutting and transitional subgrade in permafrost region and provides reference for future construction in permafrost regions.
