VERTICAL AND HORIZONTAL STRESSES DUE TO COMPACTION OF BACKFILL AND ITS INFLUENCE ON BEHAVIOR OF BURIED STRUCTURES.

Together with development of bridge structures interacting with backfill material (integrated and buried bridges), the importance of determining the actual behavior of compacted backfill of the bridge structure gains importance. The properties of the backfill material and its compaction play a critical role. This article deals with the experimental determination of the maximum vertical/horizontal stress due to compaction and its influence on the behavior of backfill of the buried structure, or its horizontal stiffness.
