PROBLEM TO BE SOLVED: To provide a chemical feeding method which enables the design strength of ground to be secured by a smaller quality of used chemical solution than ever before. SOLUTION: Since the uniaxial compressive strength of the ground is increased by mixing air bubbles with a diameter of 50μm or less into the chemical solution, the design strength of the ground can be secured by the smaller quality of used chemical solution than ever before. This enables a decrease in the quantity of the used chemical solution, so that costs can be reduced. COPYRIGHT: (C)2006,JPO&NCIPI
