Chinese Abstract

邊坡為地表與水平面成ㄧ傾斜角度者,其可分天然或人為的,若地表面非水平,則重力分量會促使土壤向下移動,但當此重力分量足夠大時,或是土壤強度無法負荷時邊坡將會發生破壞行為。在許多情況下,工程師需進行計算以查核天然邊坡、開挖邊坡以及夯實土堤等之安全性。 本研究利用數值分析方法,採用既有一些程式加以修改整合,使之能模擬淺基礎位於斜坡坡頂上之承載行為。對於坐落於邊坡坡頂上之基礎進行分析,於不同參數下,求得承載力, 再回歸推得承載力因子Nc、Nq、Nr,並將水平基礎分析得到之承載力因子與之比較,分析其折減趨勢。 研究參數針對坡角、斜坡高度、基礎位置、基礎埋置深度與土壤材料參數(c、 、Ψ)等,進行分析。研究結果顯示土壤參數在砂土中,惟有摩擦角、剪脹角與單位會影響承載力,而黏土中僅有凝聚力會造成影響。當基礎位於邊坡坡頂上時,承載力減少程度與坡角β之影響最顯著。隨著坡角增大,造成承載力折減的幅度也更大。
