摘　　要：路堤作为公路等工程的基本工程单元之一,为认识清楚路堤整体稳定性的主要影响因素及影响关系,通过选取路堑边坡的6个重要影响因素,依据正交法建立影响因素规则可比的路堤稳定性计算模型,可较为明晰地分析各影响因素的敏感性及影响关系,分析表明地震力、路堤边坡坡度、地面坡度、地基土摩擦角是主要影响因素,勘察设计过程需加以重视。As one of the basic engineering units of highway and other projects,in order to understand the main influencing factors and influencing relationships of the overall stability of embankment,a calculation model of embankment stability with comparable influencing factors rules is established based on orthogonal method by selecting 6 important influencing factors of cut slope,which can clearly analyze the sensitivity and influencing relationship of each influencing factor.The analysis shows that seismic force,slope of embankment slope,ground slope and friction angle of foundation soil are the main influencing factors,and attention should be paid to the process of investigation and design.
