PROBLEM TO BE SOLVED: To provide an estimation method of modified soil strength, in manufacturing the same by mixing a modifier containing a calcium compound with mud, which can estimate uniaxial compressive strength to be developed from a compounding ratio of the mud to the modifier and enables the estimated uniaxial compressive strength to agree with developed strength with high accuracy and to provide a manufacturing method of the modified soil using the estimation method.;SOLUTION: An estimation method of modified soil strength: obtains correlating equations, for test modifiers of 2 or more types, between respective amounts of calcium ion elution, which seep into water, per unit mass and uniaxial compressive strength of test modified soil with mixtures of the test modifiers and mud of an objective to which the test modifiers are added; and estimates the uniaxial compressive strength of the modified soil from the preliminarily obtained correlating equation on the basis of the amount of calcium ion elution from the modifier actually added to the mud. A manufacturing method of the modified soil manufactures the modified soil by: mixing the mud with the modifier where the amount of calcium ion elution is controlled to achieve desired uniaxial compressive strength on the basis of the correlating equation; and curing the mixture.;COPYRIGHT: (C)2014,JPO&INPIT
