摘　　要：基于plaxis软件针对新建彭湖高速K41+200软土路堤建立有限元分析模型,并开展有限元数值计算。通过分析不同填土速率、不同填土间隔时间工况下该断面的稳定与变形情况,得出该断面施工中与工后的沉降变化,并比较在不同填筑速率下施工过程以及工后的沉降变化,论证填土速率对路基施工质量的影响。Based on plaxis software,FEM model for new building Peng-hu highway K41 ＋ 200 soft soil subgrade is established. Through analyzing stability and deformation of the case in the condition of different filling speed and intervals, the paper shows the settlement changes before and after construction, and compares the settlement changes with different filling speed to verify the influence of filling speed on the quality of embankment construction.

关 键 词：填土速率 软土路基 施工质量 稳定性 沉降变形
