| 摘 要： | 随着中国污水处理事业的不断发展,钢塑复合缠绕管作为传统水泥排水管的替代产品,具有综合造价低、施工方便、环保效益好、耐久性高等诸多优点,近年来在国内各大城市的污水管网建设中得到了较快地推广.但是作为一种新型结构,这种管道应用的时间尚不长,其管土共同作用机理尚需要人们进行深入研究.本文采用有限元方法对钢塑复合缠绕管的管土共同作用机理进行数值分析,从理论上得出了埋地钢塑复合缠绕管受力后的强度变形特征,可供相关的工程实践参考.

| Abstract: | Recent years buried spiral steel plastic composite pipe has been applied to drainpipe construction of many big cities with the development of sewage treatment business in China. As a substitute for traditional concrete drainpipe, it has many merits such as relatively cheap price, convenient in site installation, beneficial to environment, perdurable work life. But as a new type structure, its interaction mechanism with ambient soils still needs investigation because its application period is not long enough. Finite element method is used for numerical analysis of the interaction of buried spiral steel plastic composite pipe with ambient soils. Strength and deformation characters of buried spiral steel plastic composite pipe and ambient soils are obtained theoretically. Corresponding results can be referenced by related engineering practice. |
