碩士 / 國立成功大學 / 土木工程學系 / 105 / By means of the finite element code FLOW-3D, the tsunami propagation induced by a large-scale submarine landslide is studied numerically. The landslide is assumed to take place by the collapse of Keelung Islet, which locates on the northeast coast of Taiwan. Using the energy equivalence principle, four densities of the collapse are considered: 3000kg/m3, 6000kg/m3, 9000kg/m3, 12000kg/m3. Because of a sudden vertical displacement of the ocean's surface, when the collapse falls into water, it would induce the tsunami propagation, and the tsunami waves will travel to the shore of the Jinshan Nuclear Power Plant (1st Nuclear Power Plant) and Kuosheng Nuclear Power Plant (2nd Nuclear Power Plant). According to the analysis results, the highest wave height will occur at 2nd or 3rd wave whether it occurs at the 1st or 2nd Nuclear Power Plant. The highest wave height at the 1st Nuclear Power Plant reaches 0.38 metres, and it reaches 2.1 metres at the 2nd Nuclear Power Plant. Due to natural topography in nearshore region of the 2nd Nuclear Power Plant, the waves will inundate and thus needing to construct a seawall to protect the nearshore region and reduce hazards.
