台灣因地理位置處於歐亞大陸板塊與菲律賓海板塊交界處，地震活動頻繁帶來許多災害，其中地震所導致的土壤液化即為其中一個例子，台灣中西部沖積平原多為粉土質砂土，其液化行為與乾淨砂有明顯的不同，且粉土質細砂受到顆粒排列與組成結構的影響，導致在相同的試驗條件下，以不同的試體重模方法或細粒料含量進行液化試驗可產生不同的結果，本研究以取自雲林麥寮台塑六輕的麥寮砂(Mai-Liao Sand, MLS)來代表台灣中西部粉土質砂土進行液化強度試驗，以霧式霣落法(mist pluviation)重模不同細粒料含量試體施做Ko狀態單剪液化試驗，以得到模擬現地應力條件與堆積情形下不同細粒料含量的粉土質砂液化行為與強度，並以取自彰化外海離岸風力發電場址之現地粉土質砂試體液化結果進行比較，藉此驗證以重模試體得到之試體細粒料含量與液化行為間關係，以便於協助台灣對粉土質細砂液化強度與液化特性之推估。

Taiwan is located at the junction of the Eurasian Plate and the Philippine Sea Plate, result in frequent earthquakes and relevent disasters like liquefaction. The type of sand at southwest Taiwan is silty sand, and its liquefaction behavior is significantly different from clean sand because of the effect of particle arrangement and compositional structure, which lead to different results in liquefaction test with different reconstitute method or fines content. To simulate liquefaction resistence and behavior under in-situ stress conditions and accumulation conditions in different fines content. Not only use Mai-Liao sand to represent silty sand from Taiwan southwest, this study also prepare specimens with different fines content by mist pluviation and conduct cyclic simple shear liquefaction test at Ko condition. Comparing test results to undisturbed specimen, which is taken from Changhua offshore wind power site. In order to estimate liquefaction strength and liquefaction properties of silty sand, Discuss the difference of soil liquefaction behavior between undisturbed soil and remolded specimens.
