The permafrost in the region of Yichun-Bei’an highway is characterized by thin thickness, high ground temperature and high local ice content, and is in the process of degradation, resulting in highway thaw subsidence and longitudinal cracking, which has a very serious impact on traffic. In order to design the observation scheme reasonably and master the variation law of temperature and deformation of permafrost subgrade, based on determining the observation scheme for temperature and deformation of permafrost subgrade, we established a monitoring system of temperature, humidity change and subsidence deformation of permafrost subgrade after construction by selecting typical permafrost observation sections along the highway, which can provide basic data for the design, construction and maintenance of highway subgrade in permafrost regions.
