Wave breaking is the most prominent feature of the ocean surface and it induces huge loads on structures. In this study, laboratory experiments in a large model scale are carried out to study wave forces on a vertical pile induced by breaking waves and non-breaking extreme waves, and to get insight the magnitude and the distribution of the wave forces, pressure transducers are installed in the face of the tested pile. The results show that in repeated experiments the wave pressures induced by the breaking waves present a wider variance compared with non-breaking waves; as the breaking density at the pile increases and the measuring point gets closer to wave crest, the variance of pressures increases; the maximum measured pressures can reach three times of the maximum hydrostatic pressure and occur at around 1.2 times of the maximum water surface. Based on the continuous wavelet spectrums of the wave pressures, different breaking phases show different characteristics: when the wave breaks far in front of the pile, its spectrum has a high frequency range with a wider vertical distribution, indicting more complicated pressures; when the wave breaks at the front of the pile, the wave force reaches a highest value.
