Abstract: This study treats on soil-structure interaction in the case of circular metal conduits buried in an elastic soil. The use of Finite Element Method (FEM) proves to be necessary to evaluate the most used theory, namely the empirical Marston and Spangler theory. For this purpose, computation sofware baed on the FEM was developed to highlight the response of such structures in terms of the influence of different parameters such as the ratio H/D (diameter on the height cover), the ratio D/t (diameter on conduit thikhness) and the soil properties constituting the embankment illustrated by the ratio Es/Eg (modulus of elasticity of the subgrade or substratum). All the parameters were studied according to two methods of staged on sequential construction. In this study a qualitative and quantitative comparison of results obtained by the two methods is undertaken. This study highlighted the rliability and power of FEM compared to the empirical Marston Spangler method as well as thneed for considering the history of the construction of the solid soil structure.
