摘　　要：基于能量变分原理,考虑板的横向剪切和地基耦合效应,建立了双参数地基上弹性中厚板的非线性控制方程。应用伽辽金法对双参数地基上四边自由矩形中厚板的非线性弯曲问题进行了探讨。数值计算中考虑了系统各种参数变化对弯曲问题的影响。The nonlinear governing equations of the moderately thick plate resting on two-parameter foundation including transverse shear deformation and coupled effect of the foundation are derived. By using the Galerkin method, the nonlinear bending behavior of the moderately thick rectangular plate with four free edges on two-parameter foundation is analyzed. The effects of different parameters of the system on static bending are considered.
