摘　　要：随着我国交通基础设施建设的快速发展,寒区公路工程面临的病害问题也越来越多。公路涎流冰病害作为冻土区亟待解决的主要工程病害之一,逐渐引起科研和工程技术人员的重视。基于前人的研究基础,归纳总结了我国公路涎流冰病害的分布区域和特点,探讨了公路涎流冰的形成机理和主要影响因素,分析了公路涎流冰病害防治措施的现状。在此基础上展望了今后公路涎流冰理论和防治的研究方向:(1)开展季节性冻融作用下区域水文、地下水流动特征、溢流发生机理和孔隙水压力变化规律研究,进一步探究公路涎流冰的形成机理;(2)开展公路涎流冰野外综合观测和各种因素(气候、水文条件、人类工程活动等)对公路涎流冰影响程度的定量分析;(3)开展新型综合防治措施的应用研究,为我国公路涎流冰病害防治提供更为有效的工程对策。With the rapid development of transportation infrastructure construction in China,there are more and more disease problems of highway engineering in cold areas. As one of the main engineering diseases to be solved in permafrost areas,highway salivary ice disease has gradually attracted the attention of scientific research and engineering technicians. Based on previous studies,this paper summarizes the distribution areas and characteristics of highway salivary ice disease in China,discusses the formation mechanism and main influencing factors of highway salivary ice,and analyzes the current situation of prevention and control measures of highway salivary ice disease.On this basis,the research direction of highway salivary ice theory and prevention in the future is prospected:(1)Carry out research on regional hydrology,groundwater flow characteristics,overflow mechanism and pore water pressure change law under seasonal freezing and thawing,and further explore the formation mechanism of highway salivary ice.(2)Carry out comprehensive field observation of highway salivary ice and quantitative analysis of the influence of various factors(climate,hydrological conditions,human engineering activities,etc)on highway salivary ice.(3)Carry out the application research of new comprehensive prevention and control measures to provide more effective engineering countermeasures for the prevention and control of highway salivary ice disease in China.
