Abstract: Meshless method is a new type numerical method of solving the Biot’s consolidation problem. On the basis of treating the essential boundary conditions with penalty method, the system equations of consolidation problem with meshless method are developed. Then the factors which influence the accuracy of nodes displacements, excess pore water pressures including the mode of nodes arrangement in the calculation domain, the shape and size of the influencing domain, the numerical integral scheme and penalty parameter are discussed. By analysis and comparisons, the corresponding value scope or reference suggestion are provided.

Key words: meshless method, penalty parameter, influencing domain of node, numerical integral scheme, mode of nodes arrangement, oscillation phenomenon
