PROBLEM TO BE SOLVED: To provide an infiltration solidification processing method of a sand ground capable of obtaining a solidified body with uniform strength by injecting chemicals with fixed concentration. SOLUTION: The infiltration solidification processing method sets an injection rate in each time by an unacceptable region occurring rate after the improvement set by purposes to be used, a chemical infiltration rate in a predetermined place calculated by K×vo×(1-R/Rmax) using an initial injection rate (vo), a coefficient on the unacceptable region occurring rate (K), a chemical infiltration surface position (R) and an improvement radius (Rmax) as a target, and injects the chemical with the fixed concentration into the ground in accordance with the injection rate.
