摘　　要：根据青藏铁路高寒、缺氧的施工地理条件和多年冻土工程性质随季节变化的规律,简要论述了高原路基工程施工时间、进度和填料选择控制的方法。特别指出多年冻土路基施工质量的控制和检测要贯穿于施工的整个过程,并要求尽可能多采用现场测试,特别是采用现代化的快速高自动化测试手段。In the light of the geographic conditions that are characteristic of exceptional cold- ness and anoxia for construction of Qinghai-Tibet Railway and the regularities of changing of everfrozen ground there with seasons, this paper describes in brief the construction time, progress and selection of filling materials for the embankment of the Railway at Qinghai-Tibet Plateau, and also points out that the quality control and inspection for construction of the embankment at the ever-frozen ground should be carried out throughout the whole process of the construction, and site inspection and tests, particularly the modern, rapid and highly automatized inspection and test means, should be applied as possible as they can be.
