台灣藉著海洋的便利與資源，於沿岸建立了許多城市與重要設施，核能發電廠因降溫需求，多將廠址設於海岸鄰近區域，然而卻因此面臨海洋災害的威脅，如：海嘯，其中由海底山崩所引發之海嘯尚缺乏足夠的了解，因此為了避免重大損失，必須更加了解其特性，以尋求應對之道。
本研究使用二維淺水波數值模式(COMCOT)模擬核三廠於海底山崩引致之海嘯侵襲下的水體運動，研究參考吳佳瑜(2008)以及Li et al (2015)之崩移物情境，探討台灣南部海域崩移潛勢情境之威脅，並確認能達到核三廠現行海嘯設計基準水位加6公尺所對應之情境條件，以掌握海嘯危害之情況；此外以一組情境分析海嘯生成階段，崩移物初始加速度對波浪生成的影響，同時觀察海嘯傳播階段之歷程，俾以掌握海底山崩造成之海嘯之特性。模式驗證部分，本研究以Lo and Liu (2017)提出之解析解來進行模式驗證，確認頻散效應存在的狀況下，COMCOT模擬結果之適用範圍。
本研究採用一組海嘯情境進行海底崩移物之初始加速度敏感度分析。結果顯示，初始加速度之影響有空間上的不同。一般而言，初始加速度越大，波浪引起之最大水面高程越大，但增加幅度有限，亦即當初始加速度大於1.0 m/s^2後，最大水面高程的變化較小。本研究分析台灣南部海域之海底山崩潛勢區對於核三廠之影響性，目前分析之三處危害度較大之情境對於廠區之危害度不大。研究採用放大崩移物厚度的方式，藉以考慮更大的海嘯溢淹情境。結果顯示，將情境LS3(位於東南部海域之崩移情境)之崩移物厚度增為原本之7.1倍時，可達到核三廠現行海嘯設計基準水位加6公尺之結果。

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.
