The invention provides a fabricated prestressed high-strength concrete anti-slip tubular pile composite structure and a construction method, and belongs to the technical field of anti-slip tubular pile composite structures in order to overcome the defects of an existing large-section pile and micro pile anti-slip technology in the aspects of side (slip) slope emergency rescue and permanent treatment. The combined structure comprises a prestressed high-strength concrete prefabricated anti-sliding pipe pile and also comprises (1) a hollow structure inside the prefabricated anti-sliding pipe pile, and a cast-in-place concrete reinforcing structure at the hollow part of the prefabricated anti-sliding pipe pile; (2) a single-row type prefabricated anti-sliding pipe pile combined structure and a cast-in-place concrete longitudinal top beam at the top of the prefabricated anti-sliding pipe pile; (3) a frame type prefabricated anti-sliding pipe pile combined structure, and cast-in-place concrete longitudinal top beam
