油气长输管道建设地区地质复杂,多处我国山地地区,此地区经常发生地震等自然次生灾害。由于我国对埋地管道地震破坏机理研究不足,特别是大口径长距离管道的抗震设计尚存在不确定性因素,这就给设计工作者带来了困难。文章借鉴国内外有关工程的经验从安全评价、设防标准、抗震措施等多个方面对长输管道抗震设计提出建议,供设计人员参考。
The long-distance oil and gas pipeline construction area is complex in geology, with many mountainous areas in our country. Natural secondary disasters such as earthquakes often occur in this area. Due to the lack of research on the earthquake damage mechanism of buried pipelines in our country, especially the seismic design of large-diameter long-distance pipelines, there are still some uncertainties, which brings difficulties to designers. The article draws on the experience of relevant projects at home and abroad for suggestions on the seismic design of long distance pipelines from the aspects of safety evaluation, fortification standard, anti-seismic measures and other aspects for the reference of designers.
