摘要： PROBLEM TO BE SOLVED: To provide a liquefaction countermeasure structure suppressing liquefaction of the ground with a liquefied layer deposited on a non-liquefied layer or suppressing ground deformation caused by liquefaction without costing a great deal.
SOLUTION: The liquefaction countermeasure structure applied to the ground with the liquefied layer 2 deposited on the non-liquefied layer 1 includes a soil improving body 3 constructed in a position, separated from the non-liquefied layer 1, in the liquefied layer. Since a grounding structure 4 grounded on or set into the non-liquefied layer 1 and allowing the soil improving body 3 to abut on the side face is constructed, a horizontal displacement difference from the soil improving body 3 is reduced even when the non-liquefied layer 1 is horizontally displaced by an earthquake. The shearing strain of a permanent liquefied layer 2A between the non-liquefied layer 1 and the soil improving body 3 is thereby suppressed, and liquefaction or ground deformation caused by liquefaction can be suppressed.

摘要： PROBLEM TO BE SOLVED: To agitate and mix soil and a solidifying material in a more reliable and efficient manner in a three-low agitation area formed by three rotating shafts.
SOLUTION: Out of the three rotating shafts 1, the rotating shafts 1a on both sides are rotated in the same direction, and the center rotating shaft 1b is rotated in the reverse direction to form a succession of agitation flow allowing improved soil to continuously flow over the whole agitation area. The rotating speed of the rotating shafts on both sides is made different from that of the center rotating shaft to cause the difference to the improved soil between both side parts and the center part of the agitation area, thus accelerating the flow of the improved soil between them. The supply quantity of the solidifying material from the rotating shaft of high rotating speed is set larger than that from the rotating shaft of low rotating speed. The rotating speed of the rotating shaft of high load is set smaller than that of the rotating shaft of low load.

摘要： PROBLEM TO BE SOLVED: To form an water-stopping layer having a high performance at a low manufacturing cost.
SOLUTION: A mixed soil is prepared by using a dehydrated cake as a viscous soil and mixing the viscous soil with the excavated soil of a crushed stone with a maximum particle diameter of not more than 30 mm as gravel material so that the blending ratio of fine particles which are smaller in a size than that of silt is set within the range of a weight ratio of 55 to 65%. The water-stopping layer is formed by compacting the mixed soil at a degree of compacting of not less than 95%. Following this procedural step, a cement curing material is added to the mixed soil at a blending ratio of 3 to 10% in terms of weight ratio. Next, the previously prepared mixed soil is evenly laid at the site and compacted with a tamping roller or a vibratory roller to form the water-stopping layer with a thickness of 15 to 30 cm. Finally, the water-stopping layers are sequentially piled up.
