摘要
管道是自来水、电力、燃气等生活必需品的重要输送工具,将管道埋置在地下合理的深度不仅可以提高管道使用过程中的安全性,还可以达到节约地上空间的目的。随着国民经济的发展,新型材料、大直径、薄壁、长距离的地埋管线结构相继出现,对地埋管道安全埋深计算理论和方法提出了迫切要求。从土的本构模型、地埋管道垂直土压力计算、管土相互作用、埋管外载、土体类型以及数值模拟六个角度综述了地埋管道安全埋深的研究进展,得出前人研究管道安全埋深问题的思路和方法,同时针对存在的问题进行分析,最后对其未来的发展进行了展望,以期为后续管道安全埋深研究提供科学、新颖、合理的意见和建议。
Pipelines are the important transportation tools of water,electricity,gas and other necessities. A reasonable buried depth of pipelines in the ground can not only ensure the safety of pipelines when they work,but also can save space above the ground. With the development of society,the buried pipeline structure made of new materials,large diameter,thin wall and extended in longdistance appears,which proposes an urgent request for the improvement of buried depth calculation theory and method. The research progress of the safe depth of buried pipeline are introduced from six aspects,including the constitutive model of soil,calculation of buried pipelines' vertical earth pressure,pipeline-soil interaction,external load,soil types and numerical simulation. Research ideas and methods in previous studies were summarized and future prospects were discussed,which may provide scientific,novel and reasonable opinions and suggestions for the safe depth research on buried pipelines in the future.
