Abstract
Saudi Arabia coastal area is highly valuable construction as a flat area covered by sabkha deposit. However, sabkha deposit has some geotechnical problems because of high groundwater level, high salt contents in groundwater, loose density, and possibility of collapsible settlement due to presence of crystals vulnerable to moisture, and ground improvement is needed to improve the bearing capacity. In this study, the characteristics of the sabkha soils in the coastal area of Saudi Arabia were analyzed and the applicability of dynamic compaction method was evaluated. Parametric study was conducted to analyze the behavior of sabkha deposit during dynamic compaction. The appropriateness of the proposed analytical solutions to estimate the depth of improvement was evaluated, and the troubles and notes in applying dynamic compaction in sabkha deposit were discussed.
