| 摘 要： | 在铆钉力法的基础上，提出计算胶接修补加筋板结构应力强度因子及胶层剪应力的解析法,对分析胶接修补的加筋板强度具有现实意义. 利用影响系数，可以得到筋条、补片及蒙皮位移的表达式，根据位移协调条件，建立联立方程，从而得到胶层剪应力及铆钉力. 通过解析式，计算裂纹尖端的应力强度因子，分析补片对结构修补的效果，综合考虑了筋条及补片对应力强度因子的影响. |

| Abstract: | Based upon the general equations of a trans-versely isotropic foundation, the stress functions and the theory of Fourier transforms, the basie displacement so-lutions for a transversely isotropic body under horizontal concentrated loads are obtained. By integration, the displacements caused by horizontal uniform, trianglar or trapezoid distributed loads acting on the strip area of a transversely isotropic foundation are obtained. With mea-sured elastic constants, graphs of relative horizontal dis-placements of a transversely isotropic foundation are com-pared with those of an isotropic foundation. Some valu-able conclusions are drawn. |
| Keywords: | transversely isotropic foundation constitutive equation displacement solution Fourier transforms |
