Title:
ADHESION STRENGTH EVALUATION METHOD OF FLUIDIZED SOIL
Document Type and Number:
Japanese Patent JP2021123959
Kind Code:
A
Abstract:
To provide an adhesion strength evaluation method of fluidized soil capable of evaluating whether or not a desired adhesion force is exhibited to a place including an underground outer wall, to which a lateral pressure is added, by measuring a lateral pressure from fluidized soil easily and in a pseudo manner at a site after filling.SOLUTION: An adhesion strength evaluation method of fluidized soil S to a prescribed wall surface forming an underground space includes: sinking a rod-like pressurized material 11 in a vertical direction from a surface of the fluidized soil S to a depth receiving a desired lateral pressure immediately after being filled into the underground space; pulling out the pressurized material 11 from the hardened fluidized soil S after lapse of a predetermined time; and evaluating an adhesion strength of the fluidized soil S based on a pull-out force of the pressurized material 11 and an area of a pressurized portion 11p.SELECTED DRAWING: Figure 2
