摘要:: 为了准确评定凹陷管道的承压能力，开展了含凹陷管道全尺寸爆破试验。试验得出凹陷管道的变形、凹陷区域应变及裂口特征等信息，从而分析凹陷管道失效行为与机理。结果表明：管道存在的凹陷，在提压后凹陷区域相比远场发生了较大应变，加剧了凹陷周围的应力集中。通过全尺寸爆破试验，确定了管道的屈服压力为 10.1 MPa，爆破压力为 10.5 MPa，结合相关标准与设计规范，确定试验用管段的许可承载压力为 3.88 MPa，为保障管道的安全运行与工程决策提供了技术参考。

Abstract:: In this paper, full-scale burst experiments were conducted on the dented pipelines to assess accurately the pressure bearing capacity of dented pipelines. After the information of dented pipelines was collected, including the deformation of dented pipelines, the strain in dented areas and the characteristics of splits, the failure behaviors and mechanisms of dented pipelines were analyzed. It is shown that in dented pipelines, strain in the dented areas is higher than that in the farfield when the internal pressure is increased, and the stress around the dent is more concentrated. Based on full-scale burst experiments, the yield pressure and burst pressure of the pipeline are 10.1 MPa and 10.5 MPa, respectively. In reference to the related standards and the design regulations, the allowable bearing pressure of the pipeline section to be tested is determined as 3.88 MPa. It provides the technical reference for the safe pipeline operation and engineering decision.
