| 摘 要： | 本文将任意四边形板单元的协调位移模式应用于半无限弹性地基上任意形状弹性地基板分析。文章提出了相应的高斯积分术解法,通过求解地基的柔度矩陈,根据地基与板之间的位移协调及静力平衡条件建立了以板的位移为未知量的有限元方程,并给出两算例。

| Abstract: | The harmonious displacement model of arbitrary quadrilateral plate element is used to analyze the arbitrary shape elastic foundation plate in the semi - infinite elastic foundation. The paper puts forward Gauss integral method to solve the foundation flexibility matrix. The finite element equation with unknown number of plate displacement is established according to the displacement coordination between the foundation and the plate, and to the condition of static equilibrium. Two examples of calculation are given. |
