Subgrade settlement is a key factor affecting the performance and safety of expressways.In this paper,the causes of subgrade settlement are analyzed from the aspects of geological conditions,climatic environment,subgrade filler and construction technology,and the construction technologies such as foundation treatment,subgrade filling,drainage consolidation and other construction technologies are emphatically studied,and the application exploration of electroosmotic consolidation technology and geosynthetics reinforcement technology is proposed.In terms of quality control,measures such as strengthening the management of construction materials and processes,monitoring,and feedback control of the construction process,and establishing and improving the quality management system are proposed.The research results can provide theoretical guidance and practical reference for the settlement construction of highway subgrade,and are of great significance for improving the construction quality of subgrade.
