| Abstract: | The deepening excavation foundation pit is required to reinforce the original supporting structure. The reinforced supporting structures are designed based on experience, and are not understanding the mechanical characteristics and influencing factors. The numerical model of deepening excavation reinforced by pile-anchor structure is established by the FEM software Zsoil to study the influence of various factors on force and deformation characteristics, including the factors are as follows: the coupling form and stiffness of coupling beams; the platform width; the embedded ratio, spacing, stiffness of second-stage piles. The results show that the coupling form of coupling beams and the platform width have a significant effect on the force and deformation of deepening excavation foundation pit. |
