Abstract:

Taking the construction of Youth Street Station of Shenyang Metro as case history, the author presents the major construction steps and key points of PBA (PileBeamArch) construction method. Due to the complex structure of the Metro station, PBA (PileBeamArch) construction method is adopted, which improves the safety and stability of the works, minimizes the deformation occurring during construction and protects the adjacent structures and buildings effectively.
