摘要：In this paper, the focused wave groups with different parameters and their actions on a vertical cylinder are experimentally studied The harmonic wave characteristics of the focusing waves are analyzed by the addition and subtraction of the crest and trough focusing waves The analyzed results show that higher order harmonics can be generated because of the interaction of component waves Nonlinearity increases with the inputted wave amplitude and the frequency width increment Further, the wave run-up around the vertical circular cylinder is experimentally studied It increases with the wave steepness and the relative cylinder diameter increase However, the variations of wave run-up around the circular cylinder are different The researches provide a reference for further numerical studies
