The rubble mound dyke’s crown wall is critical to reduce danger of wave overtopping,and the calculated results of wave forces by several Chinese and foreign codes vary greatly.Based on several wave force calculation method of rubble mound dyke’s crown wall from Chinese and foreign codes,combined with the engineering cases and the experimental data,the comparative study is carried out.The results show that：1）Under certain conditions,the distribution height of horizontal wave impact pressure calculated by Chinese codes of port is far less than that calculated by Jensen method and Pedersen method,and the results of the latter two methods are consistent with the measured height. 2）The horizontal wave force and uplift force calculated by Jensen method and Pedersen method are larger than those calculated by domestic harbor engineering method,and also larger than the measured value. 3）The total horizontal wave force calculated by Chinese codes of port is smaller than the measured value,and the calculated total uplift wave force is close to the measured value. 4）Jensen method takes into account the height of armor berm,and Pedersen method takes into account the height and width of armor berm.The two methods are relatively comprehensive,but the wave force with 0.1% exceedance probability is calculated according to the deepwater wavelength,and the calculation results are more conservative. 5）It is suggested that the important project should adopt the physical model experiment results.
