摘要
埋地管道是一种特殊的地下结构,因其埋于地下,延伸很远,抗震问题较为复杂。地震时由于管道周围土体移动而引起的管道位移使管道产生破坏,影响了人们的生产生活,造成了严重的经济损失。为了使埋地管道抗震设计更为合理,从而减小不必要的经济损失,针对地震波作用下埋地管道的不同变形,研究了各项工程参数对埋地管道变形的影响。不同地震烈度下管道的位移标准值不同,对于钢管和PE管6度时为15mm6度时为45mm,8度时为90mm,9度时为120mm;对于铸铁管,6度时为13mm,7度时为40mm,8度时为80mm,9度时为110mm,为埋地管道的布置提供了参考依据,使管道布置更加合理。
Buried pipeline is a special underground structures, because buried pipeline extends very far,its seismic problems are more complex. Earthquake pipeline displacement due to moving soil mass around the pipe causes pipe damage , affects people＇s production and life, leads to serious economic losses. To make the seismic design of bur- ied pipelines more reasonable, and reduce unnecessary economic losses, aiming at buried pipeline deformation un- der different seismic waves, this paper studies the influence of engineering parameters on the buried pipeline de- formation. Displacement standard values under different seismic intensities are different . For steel and PE pipes, the displacement standard value is 15mm for Intnsity 6, 45mm for Intensity 7, 90mm for Intesity 8, 120mm for Int- nsity 9; For cast iron pipe ,the displacement standard value is 13mm for Intensity 6 , 40mm for Intensity 7,80mm for Intensity 8,110mm for Intensity 9. The resuts give a reference to pipline arrangement and make it pipe layout more reasonable.
