Abstract
This study presents the results of an extensive laboratory model tests for lateral dynamic compaction on dry sand on the slope. At lateral dynamic compaction, the tamper strikes the surface of the sloping layer vertically in a circular path. The set consists of a steel box containing soil and a cylindrical tamper with a circular flat cross section that strikes the soil surface vertically. The Bearing capacity and crater depth are measured after the experiments. The results of laboratory tests showed that the bearing capacity of the strip footing near the slope increases after lateral dynamic compaction on the slope. Tamper energy and the distance from the point of impact to the edge of the slope have a great effect on increasing the bearing capacity of the strip foundation. If the distance from the foundation to the edge of the slope is 2.5B, the greatest increase in bearing capacity is obtained.
