PROBLEM TO BE SOLVED: To determine the proper charging amount of a solidifying material to the improved ground due to a cementitious solidifying agent or the like by a prior indoor test.;SOLUTION: A test body wherein a plurality of solidifying materials, which are increased with respect to the plan addition amount of the solidifying material, added to a spot soil sample is prepared prior to improve the ground and an indoor test for calculating a shearing wave speed and strength with respect to the test body to set the relation between the shearing wave speed Vs and uniaxial compression strength qu to calculate of a regression curve and the value of the shearing wave speed Vs calculated with respect to the improved ground immediately after improvement is adapted to the regrassion curve to grasp the strength of the improved ground to confirm an improving effect.;COPYRIGHT: (C)2005,JPO&NCIPI
