Gravel Columns, Bearing Capacity, Soil Conditions, Soil Characteristics, Lacustrine Clay
Construction on soft soils is always accompanied by the risk of significant, time-dependent settlement and bearing capacity failure. As technical knowledge has advanced, optimised ground improvement has offered significant economic advantages in reducing net settlement and resisting failure by installation of more flexible and cost-effective stone columns or sand compaction piles in the ground, rather than more rigid inclusions such as steel or concrete piles. The stiffness and strength of the subsoil around the columns is greater, and the consolidation time is reduced through shorter (radial) drainage paths.Gravel Columns, Bearing Capacity, Soil Conditions, Soil Characteristics, Lacustrine Clay
