This presentation discusses various ground improvement techniques for transportation projects. It introduces vertical drains, soil nailing, stone columns, vibro compaction, and dynamic compaction. Vertical drains like sand drains and wick drains accelerate consolidation by facilitating drainage. Soil nailing reinforces soil by drilling and grouting steel tendons. Stone columns form compacted aggregate columns to increase shear strength and reduce compressibility. Vibro compaction densifies loose sands. Dynamic compaction drops heavy weights to compact soils at depth. The presentation provides details on how each technique is implemented to improve weak soils for construction.
