摘　　要：路基冻胀是冻土地区铁路运营最为频繁和严重的病害之一。因地、因时制宜地采取针对性措施对减缓和消除冻害,保障线路平顺性非常重要。从填料、水分、温度3个角度,综述各类路基冻害防控技术的应用案例及效果、存在问题和未来发展方向,包括级配碎石填料、混凝土基床、盐化法、压力注浆、高抬道、换填、钻孔掏土置换、基床表层与基床底层的顶面防水、排水管、毛细排水结构、无砂混凝土透水结构、渗水盲沟、保温板、保温护道等措施的技术特征,适用情形和现场应用情况,以及新兴的冷阻式填料、电渗注浆/排水、真空注浆/排水、保温强化层、主动加热等措施的探索性研究及应用情况,并从设计、建设施工、运营不同阶段角度,讨论路基冻害防控技术的发展要点。Subgrade frost heave is one of the most frequent and severe damages encountered in railway operation in frozen ground regions.Reasonable measures must be taken in terms of local conditions and specific operational period to decelerate and eliminate frost heave and ensure the smooth operation of the railway line.By summarizing the progress of subgrade frost heave prevention methods,this paper clarified the application cases and effectiveness,existing problems,and future development directions.In terms of the fillers used,moisture,and temperature,the technical characteristics,applicability,and on-site application of various measures were summarized.These measures included graded crushed stone fillers,concrete subgrade,salinization method,pressure grouting,elevated track,replacement,drilling and filler replacement,top waterproofing of the surface and bottom layers of the subgrade,drainage pipes,capillary drainage structures,sand-free concrete permeable structures,permeable blind ditches,insulation boards,and insulation berms.Exploratory research and applications of the emerging cold resistance filler,electro-osmosis grouting/drainage,vacuum grouting/drainage,insulation strengthening layer,and active heating measures were summarized.Finally,in terms of the design,construction,and operation stages,the development trends in the subgrade frost heave prevention technologies were summarized.
