本文使用Ｆｏｕｒｉｅｒ积分变换，对非对称载荷作用下的Ｇｒｉｆｆｉｔｈ裂纹问题进行了研究。利用裂纹两侧的位移和应力联结条件，将问题归结为一组带Ｃａｕｃｈｙ核的奇异积分方程，通过Ｃａｕｃｈｙ反演求得了问题的精确解，在此基础上．给出了其应力强度因子的表达式。该结果可作为基本解用于求解一般裂纹系问题。

This article uses Fourier points transformation to study the cracks of GRIFFITH under the action of asymmetric load. Using the displacement and stress connection conditions on both sides of the cracks, the problem is attributed to a set of strange integral equations with the CAUCHY nucleus, and the precise solution of the problem is obtained through the CAUCHY reverse. The expression of its stress intensity factor is given. This result can be used as a basic solution to solve the problem of general cracking systems.
