With the rapid construction of urban multi-system multilevel traffic,the environmental factors to be considered for the design of the bearing platform foundation pit in the construction process of the upper traffic system are relatively complex,and the boundary conditions are relatively strict.Based on the bearing platform foundation pit project of a highway reconstruction project in Shanghai,this paper introduces the reasonable foundation pit support design scheme to solve the problems of displacement and settlement control in the existing highway and surface road during foundation pit excavation,so as to ensure the safety of road traffic.
