Summary:The invention discloses a pile foundation underpinning structure of a shield tunnel underpass building, which is used for underpinning existing building pile foundations conflicting with the shield tunnel, and the existing building pile foundations comprise existing building pile foundations conflicting with the shield tunnel and existing building pile foundations without conflicts. The pile foundation underpinning structure comprises a newly-built underpinning pile foundation, a newly-built cantilever underpinning beam bearing platform, a newly-built cantilever underpinning beam and a jacking structure. The lower end of the newly-built cantilever underpinning beam bearing platform is fixedly connected with a plurality of newly-built underpinning pile foundations, and the newly-built underpinning pile foundations are located on the same side of the shield tunnel. The newly-built cantilever underpinning beam is fixedly installed on the newly-built cantilever underpinning beam bearing platform, the jacking stru
