| 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. |
| Keywords: | composite pipe finite element model (FEM) internal pressure high density polyethylene foundation settlement |
