中文摘要：针对炸药库发生意外爆炸后地震波的传播及埋地油气管道动力响应振动过程进行了三维动态数值模拟计算分析，获得了管道的振动速度响应特性。考虑不同炸药库当量、场地介质特性、埋地管道材料及尺寸等影响因素，根据大量不同工况下的计算结果，结合振动安全判据量化分析，得到了各工况条件下埋地管道安全距离。该研究成果对于保证管道的安全可靠运行具有理论指导意义和工程应用价值。
英文摘要：
Relative literatures and accident statistics published at home and abroad
in recent years show that in addition to the natural disasters such as earthquakes,
landslides, etc., events closely relative to such human activities as wars, terrorist
attacks and blasting construction have become important reasons of oil and gas
pipeline damage and failure. Conducted are 3D dynamic numerical simulation on
spread of blasting seismic waves and dynamic response of vibration process of
buried oil and gas pipelines after accidental explosion of explosive storage and
numerical analysis on simulation results and obtained are vibration speed response
characteristics of the pipelines. Based on calculation results obtained in a
number of different conditions, such as dynamite inventories of explosive storage,
site media properties, materials and sizes of buried pipelines, etc., combined with
quantitative analysis on vibration safety criterion, safety distances of buried
pipelines are obtained in different conditions, which has important theoretical
significance and application value for safe and proper operation of buried oil
and gas pipelines.
