Analysis on Impact of Connection Modes of Pile-Plate on the Supporting Effect |
| |
| Abstract: | Relying on the built-in section project of a pile-plate retaining wall, the influence of the change in the connection mode of the hanging retaining plate in front of the pile and the pile in the pile-plate retaining wall supporting works on the slope supporting effect was analyzed. The finite element method is applied to calculate the structural internal force of two connection modes of piles and plates respectively, namely fixed support connection and hinged support connection, and then to analyze the changes in the stress state of piles and plates under the two different connection modes. The results show that the change in the connection mode of the hanging retaining plate in front of the pile and it has very light impact on the slope supporting effect. |
