Design of Buried Pipes Considering the Reciprocal Soil-Structure Interaction
This work presents a survey of the recently employed finite element models for the numerical evaluation of the behavior of buried pipes with emphasis on soil-structure interaction. The design and risk evaluation of buried pipes should consider the reciprocal interaction that exists between the flexible pipe and the adjacent soil. A great variety of analytical and computational procedures can be applied in the analysis of the soil-pipe interaction problem, from simplified models of the behavior of the soil that represent the response of the soil in terms of a discrete one- dimensional spring to more complex models that represent a continuous response in three dimensions of the soil. Similar considerations are applied to the model of the structural response of the pipe. In simplified approaches, the pipe is modeled as a flexible beam with axial, flexural, shearing and torsion stiffness and in more elaborated approaches; the pipe is modeled as a cylindrical shell with non-linear tension-deformation relationship.
