綜觀目前國內對於土壤液化所採用之評估方法甚多，然各評估方法均不相同，評估所得之結果往往差異甚大，造成在判斷土壤是否會發生液化的決策上十分困難。同時，前述之各種評估方法均為他國學者所提出，於國內之適用性則尚待進一步之釐清。通常一個液化評估方法之建立，除理論背景外，更需仰賴實際發生之液化案例，以確認其適用性。由於國內數十年來缺乏本土案例，因此更增加了設計評估上的困難。在921集集大地震中，中部地區發生大規模之土壤液化災害，引起國內工程界對土壤液化分析設計問題的高度重視。透過921集集地震中國內之液化案例資料，本研究將針對各評估方法之本土適用性作進一步探討，並提出具體建議，以提供設計者未來進行抗液化設計之參考。 In Taiwan, various methods are used in local liquefaction assessment. Since each method has different criteria, distinct results may be obtained from one to another. Such circumstances cause difficulties in determining whether liquefaction will happen or not. Meanwhile, these methods are all addressed by foreign scholars and the adaptability of each method still needs further investigation.The establishment of a liquefaction assessing method needs not only the theoretical background, but also the real case study to confirm the applicability. Owing to the lack of local liquefaction case, difficulties have always been met during the design progress in the last few decades. During the Chi-Chi Earthquake, large-scale liquefaction has happened in the middle part of Taiwan and caused great damage. This phenomenon attracts most engineers?? attentions on the difficulties of local liquefaction assessment and design. Through the local liquefaction case records from the Chi-Chi Earthquake, this study will investigate the adaptability of existed liquefaction assessing methods in local area and bring up specific suggestions for liquefaction resistance design. 研究期間：9007 ~ 9107
