Field Experience on Corrugated Metal Culverts

The behaviour of buried structures in earth embankments is related to the stiffness properties of the composite system comprising both the buried structure and the surrounding soil taken as a basic structural unit responding to loading imposed on the system. A field experience on corrugated metal culverts equipped with contractable seams has been carried out in order to verify the transfer of load to or away from the buried structure as a result of the difference in stiffness properties of the structure, with its adjacent encompassing material, and the surrounding expanse of soil
