Abstract:

This paper documents an investigation of foundation improvement by dynamic consolidation for a coastal power plant site in the southern Red Sea. The investigation comprised a field test, a subsequent loading test of the soil and associated geotechnical analyses to assess the improvement in the foundation conditions after dynamic consolidation. The technique was successfully verified as a suitable improvement method for the site soft soils which consisted of loose sands, and a soft clayey layer underlain by a loose sand and gravel layer, with a total thickness of seven meters. Bearing capacity safety factors became acceptable for all footing sizes.
