This paper describes the application of an original methodology to analyze a real case of a pipeline buried in a slope in central Italy, whose performance is largely determined by displacements of the surrounding soil. The slope is represented through a finite element model and its deformations are linked to the evolution of the groundwater pressure distributions. The pipe is modeled through finite elements by assuming the computed displacements of the slope as boundary conditions for the solution of the soil-pipe interaction problem. The computed stress-strain patterns are then compared with those deduced by means of strain measurements through vibrating wire sensors welded at critical positions along the pipeline.
