中文摘要：
影响斜坡地基上填方路堤极限承载力的因素主要有：斜坡坡度、路堤填土高度、路堤顶面宽度、路堤边坡坡度等。运用极限分析上限法对斜坡地基上不同斜坡坡度、不同填土高度、不同路堤宽度以及不同路堤边坡坡度的填方路堤极限承载力进行计算，得出了各个因素对其极限承载力的影响。研究结果表明路堤填筑高度和顶面宽度对其极限承载力的影响最大，其次为斜坡坡度的影响，而路堤边坡坡度对其影响并不显著。建议综合考虑斜坡坡度、填土高度、路堤宽度、路堤边坡坡度、极限承载力等各种因素来指导斜坡地基上填方路堤的设计与施工，以确保山区高速公路安全畅通。
英文摘要：
The primary factors analyses for the Ultimate capacity of embankments on mountain slope foundation include the slope foundation＇s grade and the height of the embankments and the width of the embankments and the slope＇s grade of embankments. According to practices experiences in the expressway construction on the mountain region, the effect of some primary factors for the Ultimate capacity of embankments on mountain slope foundation were analyzed by using upper-bound theorem of limit analysis, and some useful conclusion were obtained. Furthermore some viewpoints concerning the Construction of high embankments on mountain slope foundation are proposed.
