The invention discloses a reverse arc-shaped bulwark. The bulwark comprises a front wall and a square caisson structure, wherein the front wall is of a continuous semicircular-cylinder-shaped arc-shaped wave-ward surface structure, and the square caisson structure is arranged behind the front wall. According to a computing method for total horizontal wave force of the reverse arc-shaped bulwark, computing is performed through the following formulas that P=KPPZ, and the correction factor KP=0.91. The reverse arc-shaped bulwark has the advantages that the reverse arc-shaped bulwark is similar to a straight wall type bulwark in vertical pressure distribution, the position nearby the static water level belongs to triangular distribution, and the position below the static water level belongs to parabolic distribution; according to annular pressure distribution of the reverse arc-shaped bulwark, when a wave crest acts, the wave pressure intensity of central section of each arc is the maximum and decreases with the increase of the angle of each arc; when a wave trough acts, the wave pressure intensities are basically equal and are evenly distributed. A revised Goda formula should be adopted for computing the total horizontal wave force of the bulwark, and computing and analysis show that the total horizontal wave force of the reverse arc-shaped bulwark is about 10% smaller than the wave force of the straight wall type bulwark of the same size.
