Under the Barron’s equal strain condition

the plane model of sand-wall ground consolidation considering the effect of well resistance

combined radial and vertical flow and lateral displacement of soil is established. Based on the theory of homogeneous sand-drained ground consolidation by Tang Xiao-wu

under the condition of the consistency of average excess pore pressure at any depth

the equivalent transpositional formula of plane model of sand-wall ground is presented. Thereby

the complicated spatial problem is simplified as the plane problem. This method can reduce the amount of sand-wall elements

with only adjusting the coefficient of permeability. The effectiveness and reliability of this equivalent transpositional formula are validated by comparing the numerical solutions of FEM in case of plane strain and PDSS (plane deformation and spatial seepage).
