中文摘要：

利用复变函数方法，通过构造保角映射．研究了具有不对称共线裂纹的圆形孔口的平面弹性问题，求得在裂纹尖端的应力强度因子．在极限情形下，不仅可以还原为已有的结果．而且给出带双对称裂纹的圆形孔口在裂纹尖端的应力强度因子．

英文摘要：

By means of the complex variable function method and using the technique of conformal mapping,the plane elasticity problem about a circular hole with asymmetry collinear cracks was considered and the solutions of the stress intensity factor（SIFs） at the crack tip were obtained. Under the conditions of limitation,not only known results can be obtained but also the solutions of the SIFs at the crack tip of a circular hole with two symmetrical cracks were found out.
