| 摘 要： | 针对弹性地基上的中厚板，提供了一种内力和位移计算的新方法，将地基取为有限分层弹性体，利用Businesq空间解答计算地基接口刚度矩阵，并采用边界元法推导了求解中厚板内力和位移的数值解模型，算例结果表明，采用边界元法在收敛性和计算精度方面都有更大的优势。

| Abstract: | A new method is given for calculating the displacements and internal forces of thick plates on the elastic foundation. The soil is regarded as a layered elastomer, and the stiffness of the ground is derived by using Businesq solution in 3-D elastic half space. A numerical model for calculating the displacements and internal forces of thick plates is developed by the boundary element method. The result of numerical example shows that the proposed method has considerable advantages over other methods both in convergence and accuracy. |
