    Abstract: 近年來，由於氣候變遷之影響，極端暴雨頻頻發生，引發許多填土坡地之災害，嚴重威脅人民生命財產。本文以有限元素法PLAXIS程式及極限平衡法STEDwin程式進行暴雨模式分析，探討填土邊坡於降雨浸潤後之穩定行為。分析結果顯示，模擬填土邊坡受到降雨之影響，若僅單純考慮地下水位抬升而忽略其土壤受到降雨浸潤而導致之強度弱化，容易誤判填土邊坡之穩定性。與STEDwin相較，PLAXIS較能合理判斷填土邊坡之滑動趨勢及範圍，惟若能著重降雨浸潤之強度折減，STEDwin亦可得到類似之結果。分析結果顯示，降雨造成之填土邊坡
    Recently, the occurrences of extreme torrential rain have increased frequently and caused many instabilities of fill slope, resulting greater threatening for people around hillside. This paper studies rainfall-induced instability for unsaturated fill slop
