A good ground improvement method should be based on sound concepts and working principles. It requires the knowledge of fundamental behaviour of soils, the knowledge of various ground improvement techniques, understanding of soil-structure interaction, the knowledge of performance and limitations of available equipment and, of course, economics. This talk attempts to provide information on the above by presenting on the implementation of ground improvement works in civil engineering projects. Throughout the talk, real examples of projects completed using various ground improvement methods will be used to illustrate the applications of ground improvement methods in civil engineering projects from the more common embankment constructions to more complex projects like foundations for tank farms and buildings.The first ground improvement method to be discussed will be the consolidation method for soft cohesive soils, specifically preloading using fill with vertical drains and preloading using vacuum pressure. Subsequently, the compaction method, which is ground improvement without admixturesin non-cohesive soils or fill materials will be discussed. This method covers the dynamic compaction, vibro compaction, surface compaction, etc. Finally, the ground improvement using reinforcement methods will be discussed. This is a big topic covering methods such as vibro replacement or stone columns, dynamic replacement, sand compaction piles, rigid inclusions like controlled modulus columns, mixing methods, jet grouting, etc. Only a few selected methods will be discussed in detail.
