LIQUEFACTION COUNTERMEASURE METHOD FOR GROUND
PROBLEM TO BE SOLVED: To provide a liquefaction countermeasure method for the ground, which can greatly reduce the use amount of chemical solutions.SOLUTION: In a liquefaction countermeasure method for the ground G, chemical solution injection work, in which an injection pipe 10 is erected in the ground G and in which a chemical solution is injected into the ground G through the injection pipe 10, is repeatedly performed. The chemical solution is injected by cleavage injection and by dynamic injection in which injection pressure is periodically fluctuated, and the injection pipes 10 are erected at predetermined intervals in each of the horizontal and longitudinal directions of the ground G.
【課題】薬液の使用量を著しく減らすことができる地盤の液状化対策工法とする。【解決手段】地盤Ｇに注入管１０を建て込み、当該注入管１０を通して地盤Ｇに薬液を注入する薬液注入作業を、繰り返し行う地盤Ｇの液状化対策工法であって、薬液の注入を、割裂注入で、かつ注入圧力を周期的に変動させる動的注入で行い、注入管１０の建込みを、地盤Ｇの左右方向及び前後方向にそれぞれ所定の間隔をあけて行う。【選択図】図１
