breakwater under wave action，and observe the overtopping situation at the top of breakwater. In order to enhance the stability
of wave wall，two adjustment schemes for the section of rubble mound breakwater are presented: one for changing the form of
wave wall and increasing the weigh of it；another for optimizing the structural form of the side slope of breakwater，lifting up
the crest elevations of armour berme. The results show that lifting up the crest elevations of armour berme，some of the huge
waves are broken at the armour stone, the action force of waves to wave wall is reduced，the effect for enhance the stability of
wave wall is good.
