Theoretical analysis and calculation of foundation settlement of prestressed pipe pile on high-speed highway

This paper firstly analyzes settlement calculation theory model after the treatment of high-speed highway roadbed pipe pile,compares the settlement calculation difference between common pile foundation and composite pile foundation,and determines settlement calculation of pipe pile according to common pile foundation.Secondly,it calculates and analyzes roadbed settlement after treatment according to different pile length,pile distance,and pile diameter of common pile foundation.In the end,through calculation,it finds out that the reinforcement with pipe pile can effectively control the roadbed settlement,pile diameter doesn't has great impact on the settlement,pile distance has obvious impact on the settlement,pile length has obvious impact on settlement in certain length scope.
