Influence Research on Relative Stiffness to Synergistic Effect of Newly-built Pile-slab Wall and Existing Gravity Retaining Wall
For the reconstruction of the existing railway lines as well as the new second-line projects, the issues of roadbed widening and slope reinforcement can be effectively addressed through newly-built retaining structures on the basis of existing retaining wall. Currently, there is little research on composite retaining structure, especially on the synergistic mechanism between the newly-built pile-slab wall and the existing gravity retaining wall. In this paper, a three-dimensional model is established by Abaqus software. By the stiffness variation of the retaining slab and the elastic modulus of the soil, taking the slab-soil relative stiffness as the control variable, the influence law of soil arching effect behind the pile-slab wall and the synergistic effect of the composite retaining structure are studied. The results demonstrate that the stiffness of the retaining slab decreases, while the soil arching effect increases. Considering the stiffness of the retaining slab and the elastic modulus of the soil, when the slab-soil relative stiffness is between 63 and 100, the synergistic effect and soil arching effect are the optimal.
