The mooring stability conditions of breakwater cover waters have a significant impact on the safety of ships entering and leaving ports and berthing operations.How to accurately simulate the wave height distribution behind the breakwater is of great significance to engineering design.By means of test and numerical simulation,we discuss in depth mooring conditions behind the breakwater with an armor layer of accropode.Based on the physical model test,we use the SWASH model based on the non-hydrostatic equation to numerically simulate the wave height distribution in the engineering area,and represent the accropode armored breakwater by three methods in the SWASH model,such as the accropode armored breakwater passing through pore layer,topography and pore layer combination and equivalent bottom friction coefficient.Then we use the MIKE 21 BW model based on Boussinesq equation to simulate the wave height distribution in the actual engineering area,and the results are compared with those of the non-hydrostatic model.The results show that the equivalent bottom friction coefficient method in the SWASH model based on the non-hydrostatic equation is more advantageous and applicable in the study of harbor basin mooring stability in practical engineering.
