【摘要】 埋地玻璃钢管的环刚度是其抵抗径向变形的重要性能参数,影响着其外压承载能力。本文就埋地加筋玻璃钢管道的环刚度进行理论分析,所得计算式与实验方法分析获得的计算式基本一致,验证了加筋管环刚度实验分析方法的合理性,其研究方法与结果将对埋地玻璃钢管道的设计、生产与使用提供一定的参考作用。更多还原

【Abstract】 The ring stiffness is an important performance parameter of buried FRP pipes,and also the resistance to radial deformation,affecting bearing capacity under external pressure. In this paper,ring stiffness is analyzed theoretically,and the formula are basically the same with that of experimental analysis,which verified the rationality of experimental analysis and calculate methods of reinforced FRP pipeline. And,the research methods and results will serve as a reference to the design,manufacture and application of FRP pipeline.更多还原
