The invention relates to a steel pile integral shipment process under a stern leaning state of a ship, which comprises the following steps of: 1, placing a cushion block, a support pier, bottom-layercross beams and bottom-layer upright posts; 2, hanging the steel pile on the bottom-layer cross beams; 3, installing middle-layer cross beams and middle-layer upright posts on the bottom-layer uprightposts; 4, hanging the steel pile on the middle-layer cross beams; 5, after the upper-layer cross beams are installed on the bottom-layer upright posts, abutting the steel pile into a transport wholebody; 6, installing a cushion pier and a trestle on the deck of the ship under the stern leaning state of the ship; 7, driving a self-propelled modular transport vehicle to the bottom of a transport frame and passing through the trestle; 8, continuously driving the self-propelled modular transport vehicle until the vehicle is completely on the ship; 9, placing the transport frame and the steel pile on the cushion pier, and then driving the self-propelled modular transport vehicle into a barge; 10, shipment and fixing, and dismantling the trestle. The process not only solves the problem of lower shipment efficiency of the steel pile by using a guide pipe frame, but also improves the shipment efficiency of the steel pile when the barge leans to the wharf.
