Abstract
Subgrade defects classification is one of the important means for highway management and maintenance departments to prevent and reduce disaster, and it is also the basis for using engineering analogy methods to prevent subgrade defects. For this reason, firstly, subgrade defects are divided into slope defects and subgrade subsidence defects according to the definition. and the existing subgrade defects classification methods are divided into single-factor index classification method and multi-factor index classification method, and through comparison, it is concluded that the multi-factor index classification method is better. Finally, the prevention and control measures of the existing subgrade defects are summarized from three aspects: optimization design, foundation reinforcement and improvement of drainage facilities. This will provide reference and ideas for the classification and prevention of subgrade defects.
