was 5 mm greater than the original diameter. Due to the eccentricity of the initial
detonation point, the distance between the center of the crater and the top surface of
the foundation was found to be 248 mm, which was slightly smaller than 250 mm.
12.3.2.2 C-12 Specimen
The test condition of C-12 specimen was identical to that of C-11 specimen, in
which 1 kg TNT was detonated at the surface of the column with the burst height
of 250 mm from the foundation ground to the charge center. Figure 12.8 shows the
