摘　　要：介绍了国内外冻土地区管道工程技术现状,针对冻土地区管道沿线和周围(岩)土的冻胀和融沉问题,提出了相应的对策。以格拉输油管道为例,探讨了冻土地区管道工程可选择的敷设方式、油气管道的电保护技术、气候和环境变化对管道的影响以及沿线环境管理等方面的问题。This article introduces the status quo of engineering and technology of foreign pipelines in permafrost regions,and puts forward the relative countermeasures for the construction of pipelines in the regions in allusion to the frost heaving and thaw settlement of country rock and soil along the pipeline route. Take the Gelmud-Lhasa Product Oil Pipeline as an example,the authors study and discuss some technical problems about pipeline construction in the permafrost region,including pipe laying methods to be selected,cathodic protection technology, weather and environment variation along pipeline route and environment control of pipeline route.
