| Abstract: | Based on the nonlinear finite element software ADINA, the construction process of excavation and supporting of the composite soil nailed wall composed of soil nailing and cement-soil piles for deep foundation excavation is simulated through establishing a whole three-dimensional finite element model. The influence of the horizontal displacement of excavation face, the subsidence displacement of the ground beside the foundation pit ,the bottom heave displacement and the axial forces of soil nails on different pile diameters and inserting depths are analyzed. Some valuable conclusions are made, which can be used for ref- erences by engineers in the design and construction of composite soil nailed walls. |
