摘　　要：根据焦炭塔塔顶馏出管线每２ｈ记录１次的２１０６８个随机温度数据，进行了载荷时间历程的压缩、雨流法计数及统计分析。进而编制出这管线低－高－低１７级温度载荷谱。According to 21068 random temperature data recorded every two hours from a top distill off pipeline of coking towers, the temperature load time history was compressed and counted by rainflow method as well as statistically analysed. Furthermore, 17 step temperature load spectrum was compiled for the pipeline. The spectrum provides reliable basis for calculating stresses and crack propagation life of thermal variable amplitude fatigue and for carrying out safety assessment for the nozzle region adjacent to the block coke valve of a coking tower.
