有鑑於日本福島第一核電廠事故，核電廠內之用過燃料池液體被潑濺至燃料池外，使燃料棒無法冷卻，造成此事故原因之一，故本研究將大型儲槽縮尺模擬成核電廠之用過燃料池進行試驗，希望透過加裝擋板之耐震策略降低儲槽內液體潑濺，並且能夠應用於工業儲槽，為了解儲存液體大型儲槽安裝垂直擋板是否有效降低潑濺高度，本研究透過振動台試驗探討分析擋板參數對於液體之潑濺高度、頻率，及阻尼比之關係。本研究將介紹試驗中採用之擋板設計及規劃、擋板的受力變形分析和模態分析結果；採用電容式波高計量測動態水位，作為本次數據分析的重要儀器，並透過一系列的波高計測試及使用方法以了解波高計的性能及操作。
本研究探討方形和矩形儲槽在不同水深下，垂直擋板相關參數對於液體潑濺高度、對流模態頻率及阻尼比之影響，擋板參數包括；擋板插入深度、擋板與儲槽壁間距、擋板開孔特徵，經由實驗數據分析及整理，可歸納出擋板對於儲槽內液體潑濺行為的影響，提出垂直擋板各參數應用於矩槽之建議。

In light of the Fukushima Daiichi nuclear power plant incident in Japan, where used fuel pool coolant was splashed outside the fuel pool, leading to inadequate cooling of the fuel rods and contributing to the accident, this study aims to conduct scaled experiments using a large storage tank to simulate a used fuel pool in a nuclear power plant. The goal is to investigate the effectiveness of seismic strategies involving the installation of baffle plates to mitigate liquid splashing within the tank.
To determine whether the installation of vertical baffle plates in large liquid storage tanks is effective in reducing splashing heights, this research employs vibration table experiments to analyze the relationship between baffle plate parameters and splashing height, frequency, and damping ratio of the liquid. The study presents the design and planning of the baffle plates used in the experiments, along with the analysis of baffle plate deformation under load and modal analysis results.
Dynamic water levels are measured using capacitive wave gauges, which serve as essential instruments for data analysis. A series of wave gauge tests and methodologies are employed to assess the performance and operation of the wave gauges.
This study explores the impact of various parameters of vertical baffle plates on liquid splashing height, convection mode frequency, and damping ratio for both square and rectangular tanks at different water depths. The baffle plate parameters include insertion depth, distance from tank wall, and opening characteristics. Through analysis and organization of experimental data, the study draws conclusions regarding the influence of baffle plates on liquid splashing behavior within the storage tank, providing recommendations for the application of vertical baffle plate parameters in rectangular tanks.
