摘　　要：针对冻土区埋地输油管道将遇到受土体冻胀和融沉破坏等一系列特殊问题,综述了管道周围土壤水分场、温度场、应力场及三场耦合的研究现状,介绍了冻土区埋地输油管道与水热力三场的关系,分析了目前与冻土区埋地输油管道三场研究相关的研究成果。结合埋地输油管道在实际运行中的油温变化等因素,提出了未来关于冻土区埋地输油管道三场研究的几点建议,以期为冻土区埋地输油管道的设计、建设与运行提供参考。In allusion to a series of special issues in oil pipeline located in permafrost region in where the pipeline will run into damage from soil heaving and thaw-settlement,research situation in moisture field,temperature field and stress field (3-field) of the soil around the pipeline and the 3-field's coupling are reviewed.The relationship of the oil pipeline buried in permafrost region with the 3-field is introduced and current relative research achievements about the 3-field with the oil pipeline in permafrost region are analyzed.Some suggestions about future study on the 3-field for permafrost region's oil pipeline are presented in order to give a reference for design,construction and operation of the oil pipeline in permafrost region.
