Abstract: The progress in research on assessment 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.
