摘　　要：在建筑结构设计中，筏形基础板的计算一般采用有限元法和图表，在理论上没有一般性的解析表达式。本文由边界积分法给出了一般封闭解析解的表达式。作为算例，求解了有六个点作用集中力的弹性地基上四边简支的厚板弯曲问题，并相应地以图表的形式给出了计算结果。与有限元结果进行对照证明本文给出的一般性的封闭解析解的表达式是正确的。In architectonics, the calculation of bottom plate of raft foundation, in common, assumes the finite element method and figure. There is no universal analytic formula in theory. This paper offers the universal analytic formula for thin and thick plates with the method of edge integration. By an example, this paper solves the bending problems of four edges simply supported thick plate, which is loaded by six point forces on spring base. Also it giw：s the calculation solution by the mode of chart. And this solution is contrasted with that of finite element method. It is proved that the universal analytic formula is right.
