| 摘 要： | 由于钢管质量、材料性能、内压、意外载荷等因素的不确定性，实际管道总存在一定的失效概率和可靠度。介绍了利用失效评估图和蒙特-卡罗法计算管道可靠度的一种方法，并采用国外目标可靠度指标对西气东输管道的可靠度进行了预评估，结果表明：无论是否存在一定概率的漏检缺陷，西气东输管道的可靠度完全可以满足标准要求；为了提高钢管的可靠度，应在钢管制造及焊接施工过程中严格把关，以避免因人为因素造成缺陷漏检。

| Abstract: | The actual pipeline generally occur certain failure probability and reliability due to the indetermination of pipe quality, material property,internal pressure,accident load etc...It introduces a method that use failure evaluation chart and Monte Carlo method to calculate pipeline reliability and pre-evaluate the reliability of West-East Gas Transmission Pipeline by adopting target reliability abroad.The results show that the reliability of West-East Gas Transmission Pipeline fully meets requirements of specification whether it exist certain probability of defects failure inspection or not;In order to improve reliability of pipes,strict inspection shall be performed through manufacture of pipes and welding during construction of pipeline to avoid defects failure inspection caused by man. |
