摘　　要：通过对山西地区公路路堤影响因素的概括总结,选取6个主要因素进行正交组合分析,通过电算软件计算路堤整体稳定性,极差分析结果表明地基土摩擦角、水平地震力、路堤边坡坡度、地面坡度,勘察设计过程中应格外重视路堤高度、地基土粘聚力。By generalizing and summarizing the influencing factors of highway embankment in Shanxi,six main factors are selected for orthogonal combination analysis,and the overall stability of embankment is calculated by computer software.The range analysis results show that special attention should be paid to the friction angle of foundation soil,horizontal seismic force,embankment slope and ground slope in the process of survey and design,embankment height and foundation soil cohesion.
