摘要: 寒区路基长期受冻融循环、温度交变与动力荷载耦合作用,填料力学性能退化是诱发冻胀、融沉、翻浆等病害的核心原因。本文以“病害机理–防治技术–监测预测”为主线,系统梳理寒区路基填料冻融劣化、动力–温度耦合效应、固废资源化及智能防控等研究进展,剖析各类研究方法的优缺点与适用场景,补充新型保温材料、结构优化等防治内容,结合可视化图表提炼核心规律。研究表明,该领域正朝着多场耦合机理深化、绿色资源化、智能监测预测方向发展,后续需攻克极端环境填料耐久性、多技术协同防控等难题,为冻土区路基工程建设与养护提供理论支撑。
Abstract: Subgrade in cold regions is long-term subjected to the coupling effect of freeze-thaw cycles, temperature alternations and dynamic loads. The degradation of mechanical properties of fillers is the core cause inducing typical distresses such as frost heave, thaw settlement and frost boiling. Taking the thread of distress mechanism-prevention technology-monitoring and prediction, this paper systematically reviews the research advances in freeze-thaw deterioration of cold-region subgrade fillers, dynamic-temperature coupling effect, solid waste resource utilization and intelligent prevention and control. It analyzes the advantages, disadvantages and applicable scopes of various research methods, supplements the prevention contents including novel thermal insulation materials and structural optimization, and extracts core laws via visual charts. The results reveal that this field is developing towards the deepening of multi-field coupling mechanism, green resource utilization and intelligent monitoring and prediction. Future research needs to overcome key difficulties including the durability of fillers in extreme environments and multi-technology collaborative prevention and control, so as to provide theoretical support for the construction and maintenance of subgrade engineering in permafrost regions.
