摘 要:结合石忠高速公路高液限土路堑边坡特殊的工程性质,利用FLAC对边坡进行了前期稳定性分析;得到了一定坡度下坡高与安全系数的拟合关系式及一定坡度下边坡的临界高度,为沿线路堑边坡的稳定性评价提供理论依据。分别模拟了削坡和挡土墙处治边坡的过程,并对边坡的稳定性及处治效果做出评价,为采用合理的处治措施提供依据。With reference to the special nature of the high liquid limit soil cutting slope in Shizhong Expressway, FLAC is used to analyze the preliminary stability of the slope. In terms of a certain gradient slope, the formula of relationships between the slope height and the safety coefficient, and the critical height of the slope gradient are got,which offers a theoretical basis to the assessment of slope stability. Slowdown slope and retaining wall are simulated to deal with the slope. The evaluation on slope stability and the treatment efficiency are made,which offers a theoretical basis to the reasonable measures of treatment.
