    Abstract
  • The compression deformations and interaction of the subgrade and groundsill were considered at the cut to fill location, a finite element model of subgrade deformation was established by using ANSYS software, the influence rules of the vertical space and length of geogrids at cut location on subgrade were simulated, the field test and subsidence track observation at different test sections were carried out, and the influence of geogrids layer number on the unequal settlement of subgrade was studied. The result indicates that when the vertical space of geogrids is 0.8~1.0 m, the change of vertical displacement for pavement is slower, the unequal settlement of subgrade is less, so it is recommended that the rational vertical space of geogrids is not bigger than 1.0 m; the smallest chose length of geogrids at reinforcing end in cut section is 2 m for economy because the influence of the length change on the vertical displacement of pavement is less; the unequal settlement of subgrade can be reduced effectively by burying a layer of geogrid at the bottom of 96 area and 94 area respectively.
