In order to solve the problem of low efficiency of vacuum pre-compression method caused by poor drainage due to easy twisting,wrong cracking and bending of traditional drainage board in the process of soft foundation treatment,this paper proposes a new type of drainage body model,which increases the water flux,sectional modulus,and stability under the premise of reducing the amount of material.MIDAS finite element software was used to compare the mechanical properties of the traditional drainage board and the new drainage body,and PLAXIS 3D finite element software was used to analyze the applicability of the traditional drainage board and the new drainage body for drainage consolidation in the soil.The simulation results show that the mechanical properties of the new drainage body such as bending,torsion and deformation resistance are better than those of the traditional drainage board as well as its water flux and drainage consolidation rate in the soil body are better than those of the traditional drainage board.
