本文在分析了已收集到的世界各国埋地管道地震应力计算公式的基础上,提出了合理的计算公式。并将这些公式用于唐山地震中秦皇岛—北京输油管道震害验算。验算结果说明某些国外的计算公式存在着较大的偏差。 文中所推荐的公式是否最为合理,需要通过更多的震害实例进行验证。推导的公式在理论上是有根据的,计算结果与唐山震情较为符合。 Based on the analysis of the collected seismic stress calculation formulas of buried pipelines in various countries in the world, a reasonable calculation formula is proposed. These formulas are used to check the seismic damage of Qinhuangdao-Beijing oil pipeline in Tangshan earthquake. Check results show that some foreign formula there is a big deviation. Whether the formula recommended in this article is the most reasonable needs to be verified by more earthquake damage examples. The deduced formula is theoretically based on the calculation results and Tangshan earthquake conditions more in line.
