Study on Mechanical Behavior of Plastic Pipe Reinforced Cross-Winding Steel Wire Subjected to Non-Axis Line Symmetric Surface Load on Soil

Abstract:

Plastic pipe reinforced by cross helically wound steel wires (PSP) is a new plastic-matrix steel composite pipe developed in China recently. To deeply understand the mechanical properties of buried PSPs, a finite element model of PSP subjected to non-axis symmetric load is proposed. The model is verified by replacing the parameters of PSP by those of steel pipe. A good agreement shows that the model can be used to analyze mechanical behavior of buried PSP. Finally, the influences of internal pressure, properties of soil, geometry parameters of PSP and magnitude of load, etc. are discussed.
