摘要:
管道在断层错动作用下容易产生较大的位移，从而导致管道因较大的应变而失效，因此研究断层作用下管道的应变计算方法对穿越断层长输管道的设计与安全评估具有重要意义。理论解析计算方法计算简单、效率高，因而在长输管道的初步设计中应用广泛。简要介绍了Newmark-Hall方法、Kennedy 方法及Karamitros 方法3 种应用较为广泛的管道应变理论解析计算方法，并与有限元结果进行对比分析，从管道穿越角、管道埋深、土壤类型及管材类型4 个方面讨论了3 种理论解析方法在走滑断层情况下的适用性。结果表明：Newmark-Hall 方法、Kennedy 方法适用于分析管道穿越角β<45°且断层位错量较大时的断层错动影响；Karamitros 方法整体上具有较好的适用性；当穿越角β>45°时，前两种方法的适用性极其有限，应该选择模型相对复杂的Karamitros 方法进行计算。
