摘　　要：在求解无拉力地基上结构相互作用问题中线性互补方程解法,已被证明是一种很有前途的方法.它不受结构与地基本身的假定、离散方式等制约.本文的目标是将线性互补方程结合边界无法应用于分析无拉力Winkler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 analyse the thick plate on unilateral Winkler foundation with three generalized displacements. The Linear Complementary Equation ( LCE ) can be combined with BEM, FEM or other methods, which has shown great application prospects to solve this kind of problem. Three simplified boundary conditions on free edges have been derived for removing the coupling of the functions F and f, so this paper gives a satisfactory method for solving the problem of thick plate on unilateral Winkler Foundations.
