Study on Influence Parameters of Embankment Displacement and Stress in Slope Subgrade Slope

The finite element numerical models of slope embankment slope are established by the analysis software ANSYS,and the influence of different embankment slope,foundation slope,embankment height and embankment width are simulated and analyzed with the displacement and stress of embankment.The results show that:1)the slope gradient of slope embankment has little influence on the displacement and stress of embankment,and it is suggested that the slope gradient of embankment should be chosen in the range of 1:1.3~1:1.7;2)with theincrease of slope,the displacement and shear stress of embankment increase first and then decrease.It is suggested that the slope gradient of slope is less than 1:4.5;3)with the height of embankment increasing,the displacement of embankment increased.The maximum shear stress decreases first and then increases.It is suggested that the height of embankment can be chosen of 18~22 m in actual construction;4)the displacement and stress of the slope embankment increase with the increase of the width of the roadbed,and it is suggested that the width of the embankment should not exceed 20 m in practical engineering.
