<P>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. <P>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 Q<SB POS="POST">1</SB>of the modified soil obtained by the steel slag material of a loading unit L<SB POS="POST">1</SB>before being switched and a particle total surface area S<SB POS="POST">1</SB>of steel slag particles contained in the steel slag material as references, an uniaxial compressive strength Q<SB POS="POST">2</SB>of the obtained modified soil is predicted by using a partial total surface area S<SB POS="POST">2</SB>of the steel slag material of a loading unit L<SB POS="POST">2</SB>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. <P>COPYRIGHT: (C)2012,JPO&INPIT |
