The invention discloses a coast-floating trestle which comprises multiple continuously spliced coast-floating bridge sections (1) and an anchoring system (2). Each of the coast-floating bridge sections (1) comprises a coast-floating bridge box (11), supporting frames (12) and elastic material cables (13), wherein the supporting frames (12) are located on two sides of the coast-floating bridge box (11) and above the coast-floating bridge box (11), and the coast-floating bridge box (11) is suspended on the supporting frames (12) through the elastic material cables (13). The coast-floating trestle is strong in carrying capability and good in adaptability and can effectively exist and be used under the condition of moderate sea (wave height is 1.25-2.50 m).
