FOUNDATION IMPROVEMENT STRUCTURE
PROBLEM TO BE SOLVED: To provide a foundation improvement structure capable of preventing floating up of an under-ground structure in a liquefied layer.SOLUTION: A ground improvement wall 100 is formed around a common conduit 50. When an earthquake occurs and the common conduit 50 is liquefied, the soil (mud water) is prevented from being supplied. Thus, the common conduit 50 is restricted from being rotated; and thus, the common conduit 50 is effectively prevented from being floated up.SELECTED DRAWING: Figure 1
【課題】液状化層が液状化した際の地中に埋設された地中構造物の浮き上がりを抑制する。【解決手段】地盤改良壁１００を共同溝５０の周囲に設けることで、地震時の液状化の際の共同溝５０の下側への土（泥水）の供給が抑制されると共に、共同溝５０の回転が抑制又は防止されるので、共同溝５０の浮き上がりが効果的に抑制又は防止される。【選択図】図１
