To provide an investigation method for secular deterioration of chemicals injected ground that can model eluviation of liquid chemicals by ground water, and perform investigation on secular deterioration of the ground by reflecting the model.
A test piece 3 is manufactured by simulating the chemicals injected ground into which liquid chemicals are injected. Water 9 is drained from a drain pipe 7 while poured into a water tank 1 from a water injection pipe 5 to form a laminar flow with a predetermined flow rate determined using an acceleration magnification (n) in the water tank 1. The test piece 3 is installed in water 9 having the predetermined flow rate to be entirely put in the water, and after a predetermined test period passes, a chemicals concentration etc., as a characteristic value of the test body 3 is measured. The measured characteristic value is regarded as an actual characteristic value of the chemicals injected ground after a conversion elapsed period, determined by the acceleration magnification (n) and test period, so as to find an actual characteristic value of the chemicals injected ground after the conversion elapsed period.
