摘要
PROBLEM TO BE SOLVED: To provide a countermeasure structure against liquefaction of a foundation for a construction, which can stably bear the construction even if the ground undergoes liquefaction, and is implemented by drastically reducing costs for the countermeasures against liquefaction and by drastically shortening a construction period.;SOLUTION: The construction 4 is built on the ground 1 consisting of a liquidised stratum 2 and a non-liquidised stratum 3 under the same. Then soil improving bodies 5 each having a stratum thickness that is set so as to reduce a settlement of the construction 4 due to liquefaction of the liquidised stratum 2 to an allowable tolerance value or less, are formed in the liquidised stratum 2 at a location immediately below the construction 4 in a region that accommodates the construction 4 as viewed in a plan. Further, lower surfaces of the respective soil improving bodies 5 are located in the same horizontal plane.;COPYRIGHT: (C)2005,JPO&NCIPI
