针对软弱地基内摩擦角非零条件下的高速公路软土路堤稳定性问题，采用圆弧滑动稳定性分析方法，在工程中具有确定的地基岩土参数的情况下，推导了同时考虑c和φ提供抗滑力矩时的合理反压护道宽度和高度的简化计算方法。对比了考虑和不考虑内摩擦角影响的护道断面尺寸的差异，并对其滑动面特征进行了对比分析。结果表明综合考虑c和φ的分析方法更接近大部分软弱地基的实际情况，是一种实用的简化分析方法。

To probe the stability problem of highway embankment above soft soil foundation, where geotechnical parameters are available, based on the simple circular sliding stability analysis method, the simplified calculation method of reasonable loading berm width and height with considering c and φ to provide anti-slide torque is de-duced;and the Strength Swedish slice method is used for contrastive analysis of the safety factor and sliding face. The results show:the analytical methods of synthetically considering c andφis closer to the situation that the internal friction angle of soft subgrade is nonzero. the proposed method is a simplified applicable analysis method.
