Explosive Compaction (EC) involves placing a charge at depth in a borehole in loose soil and then detonating the charge.
Dynamic Compaction Techniques
Dynamic compaction is a technique used for in-situ densification of granular soil deposits by heavy impact.
Vibratory Surface Compaction
Vibratory surface compaction is a method used on the surface of a reclamation area to increase the density, shear strength, and stiffness of the fill.
Compaction is used to increase the density of fill and improve properties such as compressibility, shear resistance and resistance against liquefaction.
“Facts About Soil Improvement” describes how to accelerate the consolidation of reclaimed land increasing its strength to bear the weight of construction.
Six Sigma Quality Improvement of Compaction at the new Doha International Airport Project
The New Doha International Airport project in Qatar comprises amongst other things the construction of a 22-km2 reclamation area. The hydraulically reclaimed fill is compacted using a combination of compaction techniques, amongst which High Energy Impact Compaction (HEIC).
Ennore Breakwater Construction
Monsoons at Ennore on the eastern coast of India are a problem. Part of building the new port was the construction of two breakwaters to protect the harbour against waves and sedimentation, for which a new method of compaction was developed.
