Damage of house such as settlement or tilting by ground liquefaction has been reported every time earthquake occurs. In order to prevent from these damage, some liquefaction countermeasures have been proposed and proved these effect. However, the verification of effect haven’t been enough in the case of building houses already or for the method of reducing and suppressing damage to houses by liquefaction. Therefore, in this study, 1G model shaking table test and simplified analysis were conducted to confirm the effect of countermeasure using artificial drain pipe for existing housing ground and to establish its design method. As the result, it was possible to confirm the damaging suppression effect of the countermeasure from the model experiment, and by numerical analysis it was possible to reproduce the relative housing settlement suppression effect of liquefaction countermeasure.
