【 摘 要 】

In this paper, we present an experimental approach on the study of the evolution of residual deformations through the wall of polyethylene pipes- HDPE 80 on the mechanical behavior on one hand, and on the other hand, on the effect of chemical agents present in the soil and which can enter into interaction with the embedded tubes. The results indicate that the polyethylene is highly influenced by the presence of acids and solvents that degrade it. The modeling of constraints and residual deformations obeys to very different equations in comparison with those governing the solute shaping.
