碩士 / 國立成功大學 / 水利及海洋工程學系 / 107 / In Taiwan, most of the nuclear power plants are located near the coastal area, thus they are threatened by marine disasters such as tsunami. One of the tsunami generation types is the tsunami induced by submarine landslide which we are lacking sufficient understanding.
In this research, a two-dimensional shallow water equations model (COMCOT) was used to simulate the tsunami waves induced by submarine landslides. And the influence of the tsunami waves on the Maanshan Nuclear Power Plant was investigated. We obtained the data of the landslide from Wu (2008) and Li et al. (2015). Besides, the influence of initial accelerations was investigated. In this research we validated the range of the capabilities of COMCOT for simulating the dispersion effect of tsunami waves.
The results show that the effect of the initial acceleration is different in space. Generally, the tsunami wave height increases with the increase of the initial acceleration of submarine landslide, but the growth is limited. Three kinds of the submarine landslide for high hazard in offshore southern Taiwan were used to investigate the influence of the tsunami waves on the Maanshan nuclear power plant. The results show the hazard is small in the present study. To consider the run-up height up to the design value plus 6 meters for the Maanshan nuclear power plant, the thickness of the submarine landslides is increased. The results show the scenario LS3 with 7.1 times the original thickness could cause the desired run-up height.
