中文摘要：

以实验室模型试验为手段,测试了振动条件下输流管道周边测点动应力时程数据,得出了振动条件下输流管道周边动应力分布规律,对比分析了充液管道与空管道、刚性管道与柔性管道对动应力分布影响。测试结果表明,输流管道在下方振动波作用时,管道周边动应力分布差异较大;充液管道产生的动应力大于空管道周边产生的动应力;柔性管道产生的动应力小于刚性管道。

英文摘要：

The liquid-filled pipeline dynamic stress time history data under seismic conditions were tested by using experimental research.The dynamic stress distribution of fluid filled pipe and air pipe,flexible pipeline and rigid pipeline were coratively analyzed.The test results show that the pipeline dynamic stress distribution is quite different under ground vibration; and that the liquid filled pipeline＇s dynamic stress is larger than that of the empty pipeline,and that the flexible pipe＇s dynamic stress is less than rigid pipe strain＇s dynamic stress.
