This paper is presents the results and conclusions of the field tests conducted on a backfilled shell structure made of Super Cor SC-56B corrugated steel plates type of a road bridge located in Gimån, Sweden. The paper presents also the application of FLAC program based on finite elements method (FEM) to determine behavior of soil-steel bridge structures during backfilling. The assumptions of computational 2D model of shell structure with interface layer are described. The method based on this computational model may be used with large success to design calculations of this specific type of structures. The conclusions drawn from the tests can be helpful mostly for the assessment of the behavior of this type of the steel-soil bridge structures under load of backfilling. In consideration of an even more frequent application of this type of structure in for small and middle-sized road and rail bridges, conclusions of conducted analysis can be generalized to whole class of such structural solutions.
