This document uses previous results (which we call the first stage), for
the development of a computer model based on finite elements under the FEAP
programmer, to carry out a structural analysis of a pipeline. For this purpose,
we used environmental variables that we believe influence the failure of buried
pipelines such asthe internal pressure of fluid, the type of support used, the temperature
at which the pipelines work, the type of soil and the stiffness of the soil
acting on it. Once the model was finalized, analyses were made with each of the
variables separately and combined to observe the behavior of the pipeline,
finding the most unfavorable case that indicates the main causes that led to
its failure.
