Efficiency of weak ground reinforcement by dynamic compaction method

Abstract

This study evaluates the possibility of using fly ash, a by-product of coal thermal power plants, in the Dynamic compaction is a method that is used to increase the density of the soil when certain subsurface constraints make other methods inappropriate. The process involves dropping a heavy weight repeatedly on the ground at regularly spaced intervals. The impact of the free fall creates stress waves that help in the densification of the soil. These stress waves can penetrate up to 10 m. The degree of compaction depends on the weight of the hammer, the height from which the hammer is dropped, and the spacing of the locations at which the hammer is dropped. Most soil types can be improved with dynamic compaction. Fast construction progress, cost-effective, well-adapted to large-scale projects.
