Abstract

The subsoil conditions along the Red Sea coast in Saudi Arabia are complex due to existence of very thick beds of coralline limestone of recent geological origin. These coral beds are soft, porous and nonhomogeneous. They are often interspaced with large cavities and soft sandwiched layers of finer particles. Analysis of the subsoil conditions to a fifty meter depth based on data from deep boreholes, Standard Penetration Tests (SPT), Quasi Static Cone Tests (DCT) and large size Plate Load Tests is presented. The strength and compressibility characteristics of the strata and the correlation factors for the SPT and DCT in coralline limestone are evaluated. The results from the plate load tests conducted on natural soil and on soil compacted with stone columns are included. An evaluation of the performance of the foundation for the heavy turbines resting on soil compacted with vibro-compaction replacement method with stone columns was made.

Foundations on Stone Columns Resting on Coralline Limestone

The subsoil conditions along the Red Sea coast in Saudi Arabia are complex due to existence of very thick beds of coralline limestone of recent geological origin. These coral beds are soft, porous and nonhomogeneous. They are often interspaced with large cavities and soft sandwiched layers of finer particles. Analysis of the subsoil conditions to a fifty meter depth based on data from deep boreholes, Standard Penetration Tests (SPT), Quasi Static Cone Tests (DCT) and large size Plate Load Tests is presented. The strength and compressibility characteristics of the strata and the correlation factors for the SPT and DCT in coralline limestone are evaluated. The results from the plate load tests conducted on natural soil and on soil compacted with stone columns are included. An evaluation of the performance of the foundation for the heavy turbines resting on soil compacted with vibro-compaction replacement method with stone columns was made.
