摘　　要：基于管道极限状态可靠性评估方法,确认管道所处的极限状态,并对其在该极限状态下的各指标进行评估计算。同时,针对管道不同腐蚀状况,利用有限元分析方法,确定给定腐蚀缺陷尺寸下管道的强度,从而进一步分析管道腐蚀缺陷,有针对性地提出管道保护措施,有效保障管道的安全运行。Based on the method of pipeline limit state reliability assessment,the limit state of the pipeline was confirmed,and the indexes in the limit state were evaluated and calculated. At the same time,according to the different corrosion status of the pipeline,the finite element analysis method was used to determine the strength of the pipeline under the given corrosion defect size,so as to further find out the pipeline corrosion defect,and then the pipeline protection measures were put forward to ensure the safe operation of the pipeline.
