摘　　要：从光弹性贴片法的基本原理出发,给出正交各向异性板内任一点的应力计算公式,提出正交各向异性板厚度效应的修正系数.对带圆孔正交各向异性板孔边应力分布做了光贴片实验并与列赫尼斯基的理论计算值进行了比较,验证了方法的正确性.Based on the principle of photoelastic coating method, the calculating formulas used to determine any point of orthogonal anisotropic plate are given and the revised factor of coating thickness is proposed. The experimental result of anisotropic plate with a hole is presented by the photoelastic coating method and compared with theoretical computation values of Leheniski, and it is shown that the method is correct.
