摘　　要：给出了分析Pasternak地基上自由边矩形板弯曲问题的新方法——DQ法,运用DQ法研究Pasternak地基上自由边矩形板弯曲问题.从算例的结果看,节点个数取Nx×Ny=8×8以上,计算精度已经很高.作为一种数值计算方法,DQ法在板弯曲问题分析中具有广阔的运用前景.A new method for bending problems of rectangular plates with free edges on Pasternak foundation： the Differential Quadrature Method, is presented. With this method, the bending analysis of the rect- angular plates with free edges on Pasternak foundation is investigated. Based on the results of examples, when node number is above, the calculation precision is very high. As a numerical calculation method, this method has the prospect of wide application in analyzing the plate-bending problems.
