Analysis of Instability Treatment Scheme of Prestressed Pipe Pile on Soft Soil Foundation of Highway
Taking the A3 section of Xiapu Dongchong to Railway Station of S201(Joint 7th Line)highway as an example,this paper deeply an-alyzes the instability problem of prestressed pipe piles on soft soil foundation of highway,explores the scope and depth of subsidence area and the impact of subsidence on the surrounding environment,and carefully chooses targeted treatment schemes.The treatment scheme of subsid-ence area,pile cap scheme of unsubsidence area and pile cap scheme of subsidence area are deeply investigated.The stability of pipe pile is improved by clearing subsidence area,setting up temporary support and designing pile cap.The purpose is to provide reference for the instabil-ity treatment of prestressed pipe pile on soft soil foundation of highway.
