Abstract:

Plastic pipe reinforced by cross helically wound steel wires (PSP) is a new plasticmatrix steel composite pipe developed in China. To investigate the stress of PSP under foundation settlement, a finite element model (FEM) is proposed. The stresses and strains of PSP are obtained by the FEM analysis. The mechanic behavior of PSP subject to a foundation settlement is analyzed. Finally, the influence factor analysis of settlement deformation, such as settlement depth, overlying soil depth, diameter of PSP and inner pressure of PSP, are discussed.
