Predicting and controlling uneven settlement is a key problem to be solved in subgrade widening engineering.In view of the different treatment processes and load processes of the new and old subgrade,finite element analysis and other methods were used to explore the appropriate new subgrade treatment process,the joint stress and mutual influence mechanism of the new and old subgrade,predict the settlement during the construction period and after construction,propose the uneven settlement control scheme,and successfully apply it to the reconstruction and expansion project of Hudi Avenue.The experience can be used for reference in the implementation of similar projects.
