Abstract:	當擋土牆外移時，其土壓會重新分布；故為構築經濟及安全的擋土設施，於設計上須正確的估算土壓分布、推力及其作用位置等。為此，本研究分析20組飽和渥太華砂的三軸側向伸張試驗結果，使用其側向應變及有效側向應力之關係曲線[即( ~ )曲線模式]，預測以飽和砂土為背填土之擋土牆在不同外移量時的土壓重新分布情形。即根據牆繞底旋轉外移的幾何關係式，將外移過程中某一頂部之移動量化成；續將此值代入( ~ )曲線模式，則可求得對應此值於牆背任一深度之值，連接不同深度之即得其有效土壓重新分布圖。進而，得以計算有效 The earth pressure acts on the retaining wall will redistributions while the wall moves outwards. Thus, when a retaining wall is designed for economical and safety reasons, it is necessary to accurately estimate the involved earth pressure distribution, e
