The uniaxial compressed strength estimate methodological null sieve

摘要

PROBLEM TO BE SOLVED: To provide a method of manufacturing modified soil by predicting the strength of the modified soil appearing when a loading unit of a steel slag material is switched when manufacturing the modified soil by sing the steel slag material, and to provide a method of restoring a water area environment by utilizing it.;SOLUTION: When the loading unit of the steel slag material is switched in the middle of obtaining the modified soil by mixing in mud, with an uniaxial compressive strength Q₁ of the modified soil obtained by the steel slag material of a loading unit L₁ before being switched and a particle total surface area S₁ of steel slag particles contained in the steel slag material as references, an uniaxial compressive strength Q₂ of the obtained modified soil is predicted by using a partial total surface area S₂ of the steel slag material of a loading unit L₂ after being switched. Also, the modified soil is manufactured by the method, and it is supplied underwater to execute the repair construction of a water area environment.;COPYRIGHT: (C)2012,JPO&INPIT
