Abstract:
This paper discusses the ground improvement using stone columns for the construction of a new lattice communication tower in a gas plant in Saudi Arabia's Eastern Province. The geotechnical investigation data collected at the project site revealed subsurface conditions of loose to very loose sabkha soil with low SPT and N values (< 4) between 2.7 m and 13 m depth. Depending on the design requirements, ground improvements must be considered under the foundation of lattice towers to operate reliably and safely. The study discusses geotechnical investigations, stone column construction methods, and verification or confirmation tests used to ensure the project's successful execution. The outcomes of this study indicate that stone columns can be utilized efficiently to enhance bearing capacity and reduce settlement beneath foundations constructed on sabkha soils.
