Vibroflotation for Ground Improvement — A Case Study

A case study concerning the adoption of vibroflotation technique in a loosely filled up granular soil has been presented. The technical feasibility of the process of compaction has been established before execution of the work and the post compaction process consisted of monitoring the work by plate load tests and static cone penetration tests. The settlements of the foundations resting on the compacted granular soil have been monitored and they are well within the permissible limits. Hence this technique of compaction has been proved to be economical when compared to the adoption of deep foundation, like, the pile foundation
