摘要
无单元法是一种新方法，其在板弯曲问题中的应用，尚未见报道。本文将无单元法用于弹性地基上筏板的挠度及内力的计算中，推导了筏板的无单元法刚度矩阵公式，编制了相应的无单元法计算程序，并给出了算例。计算结果表明，无单元法解决筏板基础问题的精度是令人满意的。因此，无单元法用于解决基础板的计算问题是合理可行的。
The application of element free method to the bending problems of plates has not been found in literature. In this paper, the element free method is applied to compute the deflection and the moment of the raft, and the corresponding formulas as well as the computer program are developed. Numerical examples show that the accuracy of this method used in the foundation plate problems is satisfactory. Therefore, it is reasonable and feasible that the element free method is used in the computation of foundation plate problems.
