The invention discloses a wide-body bulk transport container and a transport vehicle. The wide-body bulk transport container comprises a front end wall (1), a back end wall (2), a left side wall (3), a right side wall (4), a box top (5) provided with a loading port cover (7), a chassis (6), a top angle piece (8) and a bottom angle piece (9), and is characterized in that a floor of the chassis (6) is reversely V-shaped on the cross section; and the left side wall (3) and the right side wall (4) are wide-body structures with widths exceeding the outer sides of the top angle piece (8) and the bottom angle piece (9), and are respectively provided with bottom side doors (10) for unloading. The side walls of the container adopt the wide-body structures, so that the space in the limit is effectively used, the volume can be increased by 5-20%, the loading capacity of the transport container is improved, the vehicle transport capacity is fully used, and the comprehensive benefit is high; and moreover, the transport container adopts an inclined chassis form and a bottom side door unloading form, can realize automatic goods unloading without needing any equipment, has no residues, improves the efficiency, and reduces the cost.
