Meshless is a new method.In this method,only a mesh of nodes and a boundary description is needed.The interpolants are polynomials which are fit to the nodal values by a least-squares approximation.The finite element mesh is totally unnecessary in this method.The essential ideal of MLS interpolants is that it is only need to construct an array of nodes in the domain under consideration.Thus,the method is completely element-free.The numerical example can indicates the method is effective.In this paper,applying it to deal with the problem of box foundation,and the corresponding formulas are achieved. The numerical results illustrate that the meshless method is used in the computation of foundation plate problems is reasonable and feasible. At the same time,it shows the advantages of the meshless method.
