摘　　要：本文用天单元法研究了弹性半空间地基板的弯曲问题，由滑动最小二乘法和变分原理导出了地基极的无单元法刚度矩阵，编制相应的无单元法计算程序，并给出算例。结果表明方法可行，且具有更加广泛的工程应用前景。In this paper, the bending problem of plates on elastic foundation os studied by use of the Element -free method. The corresponding stiffness matrix of the plate is derived using a variational principle and the movingleast -squares method and a computer program is developed. Numerical examples show that the method is feasible and has a promising prospect in engineering practice .
