摘　　要：碎石土压实后具有强度高、变形小、渗透性好的优点,在高填方路基填筑中得到广泛应用。以贵阳龙洞堡机场飞行区扩建工程高填方体为工程背景,通过数值分析手段模拟高填方体在不同施工工况下的变形情况,结合压缩蠕变试验的分析结果,对高填方体的路基压实度控制和变形规律研究有着重要的参考价值。The gravel soil is widely used in the high embankment subgrade projects because of its advantages such as high strength,small deformation and least permeability after compressed.Based on the expansion project of Guiyang Longdongbao airport,the deformation of high embankment in different construction conditions is studied by the ways of numerical simulation,combined with the compaction test＇s analysis it has important reference value to the subgrade compaction control and the deformation regularity of high embankment.
