| 摘 要： | 钢塑复合缠绕管是一种用于市政工程埋地排污排水的新型管道,在诸多性能方面优于传统的混凝土排水管,目前正在我国的城市建设中进行推广应用。这种管道外层为缠绕钢带,内层为高密度聚乙烯塑胶,是一种新型结构,在埋地受力机理方面,目前的研究做得尚不多。本文采用有限元的数值分析方法,针对不同的回填土情况,对这种管道的管土共同作用受力进行了分析,得出了填土强度对钢塑复合缠绕管管土共同作用受力的影响规律,可供相关的工程设计和施工参考。

| Abstract: | Spiral steel plastic composite pipe is a new type of pipe used for buried municipal sewage drainage project,in many aspects it is better than traditional concrete pipes,and currently applied in China's urban construction more and more widely.This pipe is a new kind of structure with a spiral steel strip on outer layer,and the inner layer is high density polyethylene plastic.The mechanism of such pipe loading in underground status needs deep research.The finite element numerical analysis method is used for d... |
