随着GB/T 20801-2020压力管道规范的更新,对于压力管道地震荷载的计算条件提出了更高的要求,本文在此基础上,总结分析油气化工码头所在地地震情况,发现大部分的码头工艺管道需要考虑地震荷载.结合工程实例,使用 CAESAR Ⅱ应力分析软件进行分析计算,并针对码头工程特殊情况,在考虑地震荷载下,详细分析了不同因素对管道应力的影响,并针对性的提出了一定的管道抗震措施.
Analysis for Influence of Seismic Loads on Process Pipelines of Petrochemical Terminal
The updated Code for Pressure Pipeline(GB/T 20801-2020)led to higher requirements for the calculation conditions applying to seismic loads on pressure pipelines.In addition to that,the field seismic situation of petrochemical terminals was summarized and analyzed,which showed that seismic loads played an role in the design of process pipelines for most of terminals.Based on engineering practice,CAESAR Ⅱ stress analysis software applied here.Subject to the special status of port engineering,the influence of different factors on pipeline stress was analyzed in detail by taking seismic loads into account,and a certain anti-seismic measures were proposed.
