冻土区埋地热油管道冻融危害及防护措施研究

摘要

基于冻土工程的特殊性,结合国内外已建冻土管道运行过程的各类风险,系统阐述了冻土管道所必须面临的5大冻害.并依据冻土管道工程的设计原则和经验,详细论证了各类冻害的防护措施.所得成果将为我国后续冻土管道工程的设计、施工及冻害防止奠定基础.%Based on the particularity of frozen soil engineering, combined with all kinds of risks in domestic and foreign existing permafrost pipeline operation process, 5 main hazards to the permafrost pipeline were introduced. According to the design principle and experiences of permafrost pipeline engineering, protection measures for all kinds of hazards were discussed.
