摘　　要：用无单元法研究了Winkler地基上带肋板的弯曲问题,由移动最小二乘法和变分原理导出了地基板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,且具有更广泛的工程应用前景.In the paper the bending problem of ribbed panel on elastic foundation is studied by using the Element-free method. The corresponding stiffness matrix of the plate is derived using a variation principle and the moving least squares method, and a computer program is developed. Numerical examples show that the method is feasible and has a promising prospect in engineering practice.
