| 摘 要： | 以弹性地基上Reissner板为研究对象,地基采用双参数模型,把地基效应归并到厚板的弯曲微分方程中。利用导出的双参数地基上厚板弯曲问题的基本解,从虚功原理出发,依据胡海昌的中厚板弯曲理论,推导出三个广义位移表示的边界积分方程。适用于任意边界条件、任意形状及任意荷载的薄板及中厚板的弯曲问题。文中给出了算例,并对各种参数变化进行了分析,获得了满意的结果。

| Abstract: | This paper discusses the Reissner’s plates on elastic foundation. The elastic foundation is considered as a medium with two parameter and its effect to thick plates is taken into account by a set of governing differential equations. According to the derived fundamental solutions for bending problem of plates on two parameter foundation, three boundary integral equations denoted by generalized displacement functions are established. This method is suitable for solving the bending problem of thin or thick plates on two parameter foundation with arbitrary boundary condition, arbitrary shape and arbitrary load conditions. |
