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.

Key words: buried pipe, spiral steel plastic composite pipe, interaction of pipe with ambient soils, numerical analysis, finite elements
