隨著人類文明快速的發展，建築結構物建設數量與密集度不斷增加，在台灣，地震災害對社會帶來的影響也日趨擴大，在所有種類的建築物中，又以核電廠受自然災害時對社會造成的影響最為嚴重，故於災害型地震後的核電廠進行快速結構診斷，將有助於核電廠的結構安全性評估，降低核安危害發生的機率。由於原始設計與真實圍阻體的動態行為並非完全相同，可於核電廠圍阻體適當位置裝設感測器，以量測真實地震事件時之結構反應，於進行健康診斷後相關參數如仍維持安全，則可加速重啟動之程序，如有損傷徵兆，亦可根據量化資訊進行補強措施。然而，一般健康診斷，通常假設結構基礎座落於相對堅實的地盤，但若考量圍阻體較周圍土層剛性，須考量土壤-結構互制效應之影響，以避免結構健康評估上之誤判。本文以PWR電廠一號機圍阻體為標的，進行訊號篩選與圍阻體搖擺行為分析，探討土壤-結構互制效應對健康診斷之影響，並根據歷次地震事件建立圍阻體健康履歷，作為未來重啟動之參考標準。

As the number and intensity of building structures continue to increase, the impact of earthquake disasters on society is also expanding. Among all types of buildings, nuclear power plants are also affected by natural disasters. Therefore, the rapid structural diagnosis of nuclear power plants after earthquake disasters will help the structural safety assessment of nuclear power plants and reduce the probability of nuclear accidents. Since the original design and the dynamic behavior of the real containment body are not the same, sensors can be installed at the appropriate positions of the containment body of the nuclear power plant to measure the structural response of the real earthquake event. After the health diagnosis, we know the real structural parameters, can speed up the process of nuclear power plant restart and strengthen the structural seismic assessment. However, in general health diagnosis, it is usually assumed that the structural foundation is located on a relatively solid site. If the containment building is more rigid than the surrounding soil, the soil-structure interaction effect must be considered to avoid misjudgments in the structural health assessment. This paper use nuclear power plants as identification targets, carries out signal screening and analysis of the rocking behavior of the containment building, discusses the influence of the soil-structure interaction effect on the health diagnosis, and establishes a health resume of the containment building based on previous earthquake events. This structural health resume can be reference standards for future restarts.
