Dike failure caused by overtopping is likely to result in major casualties and property losses. Aiming at this fact, a series of physical model experiments were conducted on stable thickness of masonry block on the inner slope of the dike. According to the erosion of block embankment with different thicknesses, the relation between the stable thickness of masonry block pitching of the inner slope and the average overtopping discharge is discussed. New equations subject to irregular waves are presented for average overtopping discharge, based upon the analysis of mean overtopping discharge and comparison of present overtopping discharge formulas at domestic and abroad. Finally, a calculation equation of the stable thickness of the dry masonry block stone of inner slope subject to irregular waves is given. In conclusion, the formula matches well with the experiment result, which is capable of functioning as an important reference for structure designs of the dike in China.
