921地震於臺灣帶來嚴重災害，使土壤液化問題受到廣泛重視，土壤液化之傳統評估方法，著重於分析數量龐大之鑽探資料，不僅需時過於冗長且所費不貲，若僅採用少數鑽孔資料進行評估則可能造成判斷錯誤；而本研究有別於傳統方式，藉由相關條件之引入，提出一簡易之液化潛能分區評估方法。

　　本研究以921地震中土壤液化嚴重之大村鄉、員林鎮、社頭鄉進行探討，採用網格分劃之方式，配合水系、地下水位、地形、土壤、沉積年代等五種圖層，施以土壤液化相關套疊分析，發展出一套初步液化潛能分區評估法，期望以較簡易且低成本之室內分析方式，區分液化潛能極高與液化潛能極低之區域，其評估結果雖趨於保守，但已具有初步區分液化潛能高低之功用，對於辨識部分特殊高液化潛能地區之效果具有一定之可信度；將此法套用於高雄市，期所得成果可供未來之相關工程作初步規劃與設計之參考依據。
