Shoreline Pilling Foundation Design in Karst Formation, Port Sudan, Red Sea, Sudan

Abstract

Coastal reef limestone almost covered the Sudan‟s coastal plain. The limestone in coral reefs shows the effect of chemical solution forming channels and caverns when submerged by Sea water. Site investigation in Dama Dama including drilling standard penetration test, geophysical survey, soils and water sampling, geotechnical properties of soils and geotechnical map had been done in this work. The overall objective of this study is to Pilling foundation designation on shoreline in karst formation for heavy constructions. Many tests have been done to confirm load predictions and account for design uncertainly includes safety factor, Settlement, Load test, Skin friction and Load Capacity. The best layer which pile should rest is coral reef limestone of weathering grade III. Therefore, it is strongly recommended to use pilling foundation in the intertidal zone and highly safety measures must be consider in building in lightly hazardous zones.
