It is known that “Blast Densification Method” is a technique which can improve the ground strength for the liquefaction by the artificial trembling with the shock wave of explosives detonation set in ground. It is carried out a full scale test which has the airport facility at Ishikari Bay New Port in Hokkaido Island, Japan.
The shaking by blasting continues for about two minutes, with 1769kg explosives, 583 delay numbers, at about 1.6 hectares experiments. It is executed safely, surely without damage to structures by blasting.
As a result of the experiment, it is confirmed the increasing excess pore water pressure, sand pumping phenomenon, and settlements after basting. This report is described a summary of experiment on this test
