| 摘 要： | 基于管线强度的衰退机理,综合分析输油管线剩余强度变化情况,构建在交通荷载作用下以竖向压力模型为基础的输油管线强度计算模型。针对兖州市输油管线的具体情况,运用Matlab软件和Excel软件分析比较不同管径下的输油管线挠度曲线和弯矩曲线,并对不同龄期的输油管线强度衰退的变化规律进行简单分析。

| Abstract: | Based on the strength＇ s recession mechanism of oil pipelines, the residual strength change is analyzed,and a computing model is established. According to the specific circumstances of oil pipelines in city,Using Matlab software, the deflection curve and bending moment curve of different oil deflection is analyzed and compared. The strength recession of different age is analyzed. |
