摘要:: 管道埋设在土体中或每隔一段间距支承在支座上,且充满或部分充满液体时,应力分析因边界条件的不确定而使结果不可靠。以管道单元的状态特性(几何性质、材料性质、载荷属性、应力分析属性等)作为基本出发点,分析了危险区管道单元的轴向、环向及45°方向应力分布状况及最大主应力,并结合弹性破坏理论,对试验区管道安全状况进行了有效的评价,给出了作为试验依据和参考的基于应变测试技术的管道力学监测试验理论。

Abstract:: Pipelines are buried underground or supported by supports at every section of distance.The result of stress analysis may become unreliable due to boundary conditions and full of liquid inside the pipeline.Taking the state characters(geometry features,material quality,load properties,stress analysis properties and so on)of a pipeline unit for a base example,the axial,circumferential,45°directional strain and maximum main strain are analyzed,and with the help of elastic damage theory to access the safety state of pipeline in the testing area and gain the theory of pipeline mechanics monitoring based on the stress testing technique,which is considered as a reference of experiment.
