blast preloading as a potential substitution for surcharge and vacuum Preloading in weak clay reclamation

The common method for land reclamation consists of application of prefabricated vertical drains (PVDs), surcharge with or without vacuum preloading. Even by applying vacuum preloading, the time needed for compilation of the project is still considered long. In this literature a new method is introduced as a new preloading agent to accelerate the soil treatment process and decrease the cost and time required for the compilation of the reclamation process. Blast preloading might be a substitution or a companion for existing methods. It was shown that blast preloading has the potential to be used in soil treatment systems, as the required time was halved in many cases and the settlement increased from ۲۰ to ۵۰ percent, in comparison to cases without blast preloading. Even in cases in the absence of surcharge or vacuum, the blast preloading acts the same as surcharge or vacuum preloading.
