In order to study the wave force characteristics of the slope type submerged embankment under different wave height and water depth conditions,based on the design and physical model data of a submerged embankment,we use FLUENT software to establish a two-dimensional wave numerical water tank,verify the reliability of physical model by the test data,calculate the wave forces of slope type submerged embankment under different submerged water depths and wave heights by a series of numerical simulations,analyze the relationship of wave force,relative wave height and relative submerged water depth,and obtain the formula for calculating the maximum wave force on the top surface of the slope type submerged embankment by fitting the numerical data combining with other forms of submerged embankments.The results show that the wave force is significantly affected by the relative wave height and relative submerged water depth,and its influence mechanism is related to the wave field fluid motion characteristics.Compared with the wave height change,the wave force is more sensitive to the change of the submerged water depth,and the wave force show different change law in different submerged water depth intervals and different action positions.
