The invention relates to a continuous multiple arc type wave-absorbing bank. The continuous multiple arc type wave-absorbing bank comprises a main body and a slope protector, wherein the upstream surface of the main body is provided with an inclined slope, and the slope protector comprises a circular-arc protecting surface and a horizontal connecting section.

The plurality of circular arcs are arranged, so that the gradual wave absorption can be realized. By virtue of a model experiment, the wave-absorbing rate can be up to 69%-82%, and the wave-absorbing effect is obvious.
