| Abstract | The coastal environment of Taiwan is more similar to that of Japan, where the seabed crust is fault and the seismic zone is more, and the earthquake along with the landslide tsunami which causes the common effect of the large rock collapse or the seabed slide will cause more disaster to Taiwan.In this study, the landslide-type solitary waves impacted by the wave-making slide were mainly, three sets undulating breakwater placed in wave flume, finally place the same size as the sink pipe breakwater, At last, the energy dissipation structure of the same size pipe hole is placed in the water tank, and is filled in front, rear and middle of each group 0.04m thick fine white sand layer, adjusts ˇ§ undulating breakwaterˇ¨ and ˇ§pipe breakwaterˇ¨ the distance, to study the sand transporting rate of the sand in the front and back bed of the landslide by using different combination conditions, and to understand the sand transporting process, brush characteristics and the evolution of the shore beach, and to assist the establishment of numerical simulation, As a reference for the future of the coastal topography changes caused by the warming of the earth and extreme climate. Experiments show that, with fine sand drift observation after splitting type solitary wave by wave undulating breakwater, different distance between submerged breakwater group b/h and pipe breakwater of w/B sand surface change as a whole, sand surface curve mainly in embankment before x = 0 ~ 25 cm range, especially before, sand surface between the rear with a submerged breakwater scour is most intense, and gradually increased when the distance between the dike group b/h, sand surface curve will gradually slow; In addition, the sand surface variation in Section II and Section III region, will w/B the distance gradually increases, decreases. |
