    Abstract
  • The horizontal displacement of geocell flexible retaining wall was analyzed by finite element method, its cut-off point in the middle of the wall was got, and the calculation method of active earth pressure under limit state was put up. The displacement mode above the cut-off point was near translational and the earth pressure of the part was calculated by Coulomb's active earth pressure theory. The displacement under the point was near rotary around the foot of the wall and the earth pressure of the part was calculated by level differential element method. The calculation results were compared with the measured results. Comparison result shows that the distribution shapes and growth trends of earth pressures from the calculation and measurement are basically same along the wall, and the calculated results are a bit smaller than the measured ones. The minimum deviation between the calculation values and measured values is 0.2 kPa, the maximum one is 2.9 kPa, and the average one is 1.2 kPa. Obviously, the calculation method is reliable.
