環太平洋地震帶包含全球 90%的地震活動外，全球 75%的火山也分布於此地帶， 臺灣 、 日本、琉球、菲律賓 等國家頻繁受地震影響，其造成之災害使國家經濟損失，人民生命受威脅，在 2011年 3月 11日於日本東部近海發生規模 9.0最大震度為 7之大地震，並引致海嘯導致大範圍交通、通訊、能源均癱瘓，其中對人類最嚴重之威脅的是造成核能電廠設備嚴重受損，除了電力無法供應之外，亦造成核輻射外洩，然而臺灣 擁有四座核能發電廠， 維護其結構 安全 是至關重要，台灣電力公司除了在圍阻體裝設地震儀之外，各場址亦建立井下地震儀震列，透過實際地震事件測資料，可針對核能電廠結構安全進行評估，在地震發生後可進行結構之健康診斷評 估，並且利用井下陣列量測資料可探討場址效應以及土壤 -結構互制之行為，本研究以建立 PWR電廠兩座圍阻體之完整健康履歷為目標，除了利用 結構量測資料 探討搖擺效應 接著同時 藉由 井下量測分析 核電廠 基地 之場址效應 以及利用地盤反應分 析程式 找出周圍 土壤 之模型 ，再 透過 圍阻體與井下測站之比較， 觀察 較大尺度大地與結構物之互動行為，最後透過不同識別模型之假設，探討受土壤 -結構互制效應影響之識別結果 建立兩座圍阻體 完整之健康履歷，以 供 未來 耐震補強之依據 。

On March 11, 2011, an earthquake with a magnitude of 9.0 and a maximum magnitude of 7 occurred off the coast of eastern Japan, resulting in a tsunami that caused serious disasters. The serious damage to nuclear power plant equipment is the most serious threat to human beings. In addition to being unable to supply electricity, it also caused nuclear radiation leakage. However, Taiwan has four nuclear power plants, and maintaining structural safety is important. Taiwan Power Company installed seismographs inside the containment building and built a downhole array at each site. Through the actual seismic event data, the structural safety of the nuclear power plant can be evaluated, and the structural health resume and evaluation can be carried out after the earthquake. The site effect and soil-structure interaction behavior can also be discussed by using the downhole array measurement data. This study aims to establish the complete health resume of the two containment buildings of the PWR power plant, and uses the structural measurement data to discuss the rocking effect. Model the surrounding soil, and observe the interaction between the surrounding soil and the structure through the comparison between the containment building and the downhole station. Finally, through the assumptions of different base identification models, the identification results affected by the soil-structure interaction effect are discussed, and the complete health resumes of the two containment buildings are established.
