摘　　要：文章基于平面假设对一种由不同材料组成的3层组合超静定梁进行理论分析,给出了组合梁的位移和应力计算公式,所得到的结果可以很容易地退化为双层组合超静定梁和单层超静定梁的情况,也可推广到任意层组合超静定梁的情况。A statically indeterminate beam composed of three layers with dissimilar materials is analyzed based on the plane cross-section assumption,and the displacement and stress formulae of the beam are obtained.The results obtained in this paper can easily degenerate to those of the statically indeterminate beam with two layers or single layer,and they can also be expanded to the case of the statically indeterminate beam with arbitrary layers.

关 键 词：多层 超静定梁 应力 位移
