摘要： PROBLEM TO BE SOLVED: To estimate the origin position gel time of a chemical injected into a ground for countermeasure against the liquefaction of the ground so that the chemical can be reliably injected into the ground within the range to be injected before gelation when the chemical is injected into the ground.
SOLUTION: An oscillator sensor unit capable of transmitting and receiving a compressional wave (P wave) and a shear wave (S wave) is installed in the ground improved by injecting the chemical therein. The gel time at the origin position of the injected chemical is estimated from the changes over time of the compressional wave velocity (Vp) among the elastic waves measured and calculated by the oscillator sensor, and the chemical is injected reliably into the ground to be injected before the start of the gelation.

摘要： PROBLEM TO BE SOLVED: To infer the strength of improved ground which is an object improved by chemical injection using an active-silica-based chemical, from its early age after the improvement, with accuracy. SOLUTION: A vibrator sensor capable of generating and receiving compressional waves and shear waves is installed, in ground to be improved by injecting the active-silica-based chemical into the ground. By using a compressional-wave velocity obtained by this vibrator sensor, and applying it to a regression curve representing relation between compressional wave velocity and uniaxial compressive strength obtained by an indoor test previously, the uniaxial compressive strength of the improved ground is inferred.

摘要： 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 50 μm 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.
