摘要
应用Mindlin板理论，考虑剪切变形的影响构造9节点等参数有限单元，对双参数弹性地基上的板基础（中厚板）进行分析，运用降阶积分的方法计算单元刚度矩阵。通过对不同厚度板进行内力分析，表明文中的方法不仅适用于中厚板也适用于薄板基础。
Based on the Mindlin＇s plate theory, the 9-node isoparametric finite element is constructed in the paper considering the effect of shearing deformation. Plated foundation （Medium-thick plate） on two-parameter elastic foundation is analyzed. The stiffness matrix of element is calculated by using the method of reduced integral. By studying the stress analysis of different-thickness plate, the result shows that the method is suitable to both medium-thick plated foundation and thin plated foundation.
