Then, according to experimental results, the comparison and discussion between present modified formula and Goda’s formula on wave pressure statistics, total wave pressure force and accuracy. From the overtopping wave pressure profile, the result shows that the wave pressure in 1/7 water depth without evidence shrink. At the aspect of wave pressure statistics and wave pressure force, present modified formula are more conformable with experiment than Goda’s formula, and Goda’s formula will overestimate the actual wave pressure force when overtopping. Present formula, Goda’s formula and Haung&Lee’s (1996) formula are more accurate than Sainflou’s (1928) formula and Yeh’s (2001) formula when calculation with the sliding factor. Come to the conclusion, present modified wave pressure formula can be suitable for calculation wave pressure in deepwater breakwaters with wave overtopping.
