The invention relates to a combined anti-collision beam comprising an inner plate and an outer plate which are buckled and which are in strip shapes. A boss is formed at the center by projecting, two ends of the boss extend along the length directions of the inner plate and the outer plate, and a plurality of arcuate projections are formed on the boss of the outer plate. The tops of the arcuate projections are arc-shaped, the bottoms of the arcuate projections are connected with the outer plate. Arcuate projection bodies of the arcuate projections span two sides of the boss of the outer plate or are arranged on one side of the boss of the outer plate.
