| Popis: |
This research is based on an anti-seepage project of landfill in Jiangsu province, China. Finite element method in ANSYS is used to investigate numerically the stress and strain of diaphragm wall in the landfill. The pulp ratio of diaphragm wall is determined by orthogonal experimental method. Results show that the maximum stress (absolute value) of the wall is only 0.24–0.38 MPa and no tensile stress is produced with the wall. The maximum horizontal displacement is in the bottom of the wall with the value about 0.19% of the height of the wall. The maximum vertical displacement is in the top of the wall with the value about 2.5% of the thickness of the wall. In addition, no plastic deformation occurs in the diaphragm wall and the deformation of wall is proportional to that of its surrounding soil, which meets the operational requirements of landfill. |
