SOLUTION: When the preconstructed tunnel (main tunnel 1) is widened, a soil improving body 4 surrounding an area to be widened is constructed. The soil improving body is constituted as a multiple structure which is composed of a reinforced portion 4A undergoing injection of a suspension-type grout material, and a cut-off portion 4B undergoing injection of a solution-type grout material; and a plurality of impervious walls 6 are formed inside the multiple structure, so that the inside of the soil improving body are divided into a plurality of impervious areas 7. In the construction of the soil improving body 4, the injection of a chemical solution is performed gradually. A steel pipe forepiling method is carried out as an auxiliary construction method in the widening of the tunnel. Cut-off performance is checked by performing a drainage test for the impervious areas in advance of the widening of the tunnel. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To realize an effective method of preventing liquefaction with excellent reliability obtaining sufficient liquefaction preventing effect.
SOLUTION: An underground water level is lowered by pumping up underground water from the ground 3 to be prevented from liquefaction, and the ground is put in an unsaturated state by injecting water 6 with a large quantity of dissolved air into the ground to recover the underground water level. The pumped-up underground water is aerated to enhance the quantity of dissolved air, and injected into the ground. Pumping of underground water from the ground and injection of water with the large quantity of dissolved air into the ground are performed at the same time. Injection of water with the large quantity of dissolved air into the ground is performed by infiltrating the water into the ground from a ground surface part. While measuring the degree of saturation of the ground, pumping of underground and injection of water with the large quantity of dissolved air are repeated until the degree of saturation reaches a prescribed set value. While monitoring the degree of saturation of the ground, pumping of the underground water and injection of water with the large quantity of dissolved air are performed based on the result to maintain the degree of saturation to the set value.
