Abstract：In this paper,a new type of breakwater structure of semi-elliptic breakwater was proposed,and a series of model tests were carried out on two different size semi-elliptic breakwater models.The aim of this study was to analyze the hydraulic characteristics of elliptic arc-shaped structural plane un-der wave action.The results provided a reference for the construction design of this new type breakwa-ter.The influencing factors of wave force of semi-elliptic breakwater were determined byπtheorem,in-cluding wave steepness H/L,relative wave height H/D and scale parameter b/L.Based on the experi-mental data,the variation characteristics of wave forces on semi-elliptic breakwater withthese three factors were analyzed and the stress characteristics of two semi-elliptic breakwater models were com-pared.The results showed that the wave force increased with the increase of H/D and decreased with the increase of H/L and b/L.The wave force in model 1 was larger,and the horizontal wave force was much larger than the vertical wave force.The wave force in Model 2 was smaller,and the horizontal wave force was close to the vertical wave force.
