摘要
采用Ｗｕ氏权函数与Ｂ样条函数相结合的方法，计算了带裂纹圆柱岩石试样在一对裂纹面内沿柱体母线作用下的应力强度因子．计算结果与文献值的比较表明，本方法不但简便，而且具有较高的精度．
The stress intensity factor of cracked cyclinder rock specimen loaded by a pair of forces along generate line of cyclinder is calculated through the combination of Wu's weight function and B-spline function. Comparison of results shows that the present method is of higher precision.
