Geomechanical behaviour of large diameter pressure water pipelines in unidimensional heterogeneous soils
Résumé
A follow-up methodology of pressure buried concrete pipelines is given in this paper. The methodology allows to acquire a better knowledge of the determining factors of the mechanical behaviour of the pipelines in order to optimise the asset management. A bidimensional geo-mechanical finite element model of a pipeline, which integrates the spatial variability of the soil, is considered to illustrate the methodology. The results show the influence of the variability of the soil on the structural integrity of the pipe at a given time.
