摘　　要：提出了应力和强度为任意分布时可靠度计算线性插值和三次样条插值相结合的方法来代替作图法．一方面提高了计算精度，另一方面克服了高阶多项式的振荡问题，使得计算结果更为合理、精确．A reliability calculation method is proposed for arbitrary stress strength distribution and the 1th order polynomial interpolation combined with the 3rd order spline function is applied to take the place of graphic representation in this paper.Calculation accuracy is improved and the unstability problem of higher order polynomial has been solved,which makes the calculating results more reasonable and more accurate.
