【Abstract】 Required by the national economic development and open-door policy, the speed of vessels sailing in inland waterway is faster and faster. However, many problems axe accompanied such as the impact of ship wave to narrow river channel. This thesis studies the interaction between ship wave and compound breakwater. Firstly, the relationship between the maximal wave pressure and swash height produced by ship wave’s impact of high-speed vessels on compound breakwater and ship wave height, wave length, and wave period is described. The intluence of compound breakwater’s platform height, breakwater width and hydrostatic level on maximal wave pressure and swash height is analyzed. Then, according to the tests of the impact of a series of regular wave on the compound section of breakwater with platforms, the empiric formula of swash height and maximal wave pressure is derived. Finally, the wave pressure and swash height is predicted with application of BP algorithms in Artificial Neural Networks, and the result of?prediction is compared with experimental data and the result from empiric fomula. This research provides an effective method and rule for the design of revetment and inland waterway with high speed vessels sailing in. The application of ANN to wave studies is a new trial更多还原
