摘　　要：以栾卢高速公路工程为依托,通过现场监测与数值模拟相结合的方法,对边坡坡脚及三级边坡处的位移变形及边坡整体稳定性进行研究,结果表明:随着斜坡面坡度增加,软弱地基土上的高填路堤边坡整体变形增大,坡度由1∶5.00变化到1∶4.50时水平位移与竖向位移变化最大,边坡出现不稳定趋势时高填路堤下软弱斜坡面坡度为1∶4.51。The Luanchuan-Lushi Expressway was used as the supporting project to study the displacement deformation and overall stability of the slope at the foot of the slope and the tertiary slope through a combination of field monitoring and numerical simulation.The results show that:with the increase of slope surface slope,the overall deformation of highfill embankment slope on weak foundation soil increases,and the change of horizontal displacement and vertical displacement is the greatest when the slope changes from 1∶5.00 to 1∶4.50,and the weak slope under high-fill embankment is 1∶4.51 when the slope becomes unstable.
