摘要
提出了一种新的间接抽样方法，既无需求出拉伸应力Pm和弯曲应力Pb的随机分布，又模拟了Pm和Pb之间隐含的相关性，从而为完成含缺陷压力管道的失效概率计算奠定了较好的技术基础。
A new indirect sampling method was proposed.It needn' t calculate the random distribution of the tensile stress P. and the bending stres Pb, simulated the correlaton between P. and Pb,and a good technical basis was made for the calculation of the failure Probability of pressure pipes with defects.
