无拉力弹性地基上中厚板的边界元──线性互补方程解法

Boundary Element-Linear Complementary Equation Mothed for Analysis of Thick Plate on Unilateral Foundation

本文将线性互补方程结合边界元法应用于分析无拉力Ｗｉｎｋｌｅｒ地基和弹性半空间地基上中厚板的弯曲问题，从三广义位移理论出发，采用文［１］提出的简化的三个边界条件，解去Ｆ、ｆ的耦联，从而使问题得到圆满解决。

The boundary element-linear complementary equation method (BE-LCEM) is proposed to analysis the thick plate on unilateral Winkler and elastic half space foundations,according to the theory of three generalized displacements, three simplified boundary conditions on free edges have been derived for removing the coupling of the function F and f, so this paper gives a satisfactory method for solving the problem of thick plate on unilateral foundations.
