摘要
介绍了概率断裂力学(PFM)在管道可靠性评估中的研究进展,总结了国内外近20年的研究成果,比较分析了两种干涉模型的优缺点。指出了管道可靠性研究的发展方向,建议采用分层抽样法获得检测样本。
The progress in research on assessnent of the pipeline safety based on probabilistic fracture mechanics(PFM) was introduced.The research results at home and overseas in the past two decades were summarized.The merits and demerits of the two interference models were compared and analyzed.The future reliability research tendency of pipeline was proposed.It is suggested that stratified a sampling method can be used to obtain a detection sample.
