Abstract:

The finite element software ABAQUS is used to establish a three⁃dimensional load⁃structuremodel to analyze the influence of supporting pile depth, supporting pile spacing, diaphram wall stiffness,column spacing on the stress and deformation of the structure under the supporting pile retaining systemand the diaphram wall retaining system. The results show that the internal force and displacement of themain structure decrease with the increase of the depth of the retaining piles in a certain range, it has littleimpact when it goes beyond this range. With the increase of supporting pile spacing, the horizontaldisplacement of the structure increases, but the magnitude of the increase decreases, and finally tends tobe stable. The increase of the stiffness of the diaphram wall can effectively reduce the lateraldisplacement of the main structure and reduce the equivalent stress of the main structural member of themain structure. The decrease of column spacing can effectively reduce the vertical displacement of thebottom plate and the maximum stress of the column.
