多年冻土特征及其路基病害分析

结合工程实际阐述了多年冻土特征及其路基病害,提出路基设计应采取保护冻土的设计原则,通过优选线路、抬高路基、设置砂砾路面、增设保温护道、完善排水系统等措施可防止或减缓病害的发生。研究成果可以为相关工程设计、施工提供借鉴。

Characteristics and Subgrade Diseases of Permafrost

It expatiates on the characteristics of permafrost and its subgrade diseases combining with engineering practice,and proposes that the design principle of frozen earth protection should be adopted in subgrade design.Through optimizing route,elevating the subgrade,setting gravel pavement,adding hear preservation path,perfecting drainage system and other measures,the diseases will be prevented and delayed.The research fruits can provide reference to the design and construction of correlative engineering.
