PROBLEM TO BE SOLVED: To provide a centrifugal loading experiment method capable of attaining a time contraction scale corresponding to a general model contraction scale, and capable of simulating properly construction of an underground concrete structure, and a test body for a centrifugal loading experiment. SOLUTION: A clay layer 9 is formed in an experiment soil vessel 1, a ground 2 comprising a crushed stone layer 11 is formed, and a channel 15 is excavated in the ground 2 to fill a solution 33 having a specific gravity substantially equivalent to that of the ground 2. The channel 15 is divided into a plurality by a thin film 17. Then, the solution 33 in channel 15a, 15b, 15c is replaced sequentially with an anaerobic adhesive 35 having 1.1-1.2 of specific gravity and excellent in affinity with a metal ion, while imparting centrifugal loading to the experiment soil vessel 1, using a centrifugal loading device 19. A granular material (not shown in Fig.) having the metal ion on its surface is made to flow into the anaerobic adhesive 35 to obtain a solidified body 37. COPYRIGHT: (C)2006,JPO&NCIPI
