Theoretical analysis and experimental research of wave force of breakwater in deep water area

Deep Water Port Development and Construction play an important role of Harbor Planning development in Taiwan District even breakwater in deep water area however, the wave force of deep water breakwater in theoretical and experimental analysis is rare to be studied so far. Probably due to unproperly use of the design theory or some major property of wave force is not considered, therefore, the real example of the failure of deep water breakwaters occured. For such case, it is necessary to analyze and to discuss the property of wave force in deep water breakwater and then makes some different characteristics from design theory of breakwater in the finite water depth. The research project mainly deals with wave force produced by regular wave to the action of deep water breakwater. By emphasizing the important character changing theory and using mathematical method to analyze the property of the high-order standing wave pressure and non-linear deep water wave pressure duration curve, in order to compare the important property of front wall and the back wall wave pressures of the deep water breakwater. For the experimental aspects, it is matched with the theoretical analysis, by using all kinds of the relation depth vs different incident wave steepness, and then to measuring the wave pressure characteristics of deepwater breakwater and discuss its important findings. Among the experiments, they involve wave pressure duration curve and wave pressure distribution of the vertical breakwater section. Especially the characteristics of the microseisms occurred from the bottom of deep water breakwater due to standing wave action. Here a detail discussion is described. In addition, the impact breaking wave pressure property is investigated in this research. The irregular wave pressure characteristics of deep water breakwater will be further studied in the next phase. The research results will propose suitably some suggestion items to the design of deep water breakwater.
