| 摘要： | Profiled polymer pipe is a three-dimensional structural form that behaves in a three-dimensional manner when subjected to soil pressures during burial. The three-dimensional response of profiled high-density polyethylene (HDPE) pipe was recently measured in a soil cell at the University of Massachusetts. The profile tested featured a corrugated section fitted with a smooth internal liner. A finite element analysis for determining the response of buried profiled pipe has been developed by the first author. The soil cell results are examined using the three-dimensional finite element analysis. Distributions of circumferential and axial stress and strain are considered in the profiled pipe and in the soil surrounding it, and different responses of the corrugation and the liner are examined. The analysis is used to examine performance limits for profiled HDPE pipe under large hoop compressions. |
