RESEARCH ON OPTIMUM DESIGN AND APPLICATION OF DOUBLE-ROW PILE RETAINING STRUCTURE
A fundamental theory,simple model and stress analysis method for the double-row pile retaining structure design are introduced.The finite element software ANSYS was used to set up the model of double-row pile retaining structure.By analyzing the effects of the spacing,pile rigidity and other factors on the deformation and bending moment of the structure,some conclusions were obtained.Through effective co-action of double-row piles and soil,the double-row pile retaining structure has larger lateral stiffness.The performance of pile retaining structure is influenced by the spacing between pile lines,so the spacing should be reasonable.
