每次地震发生时，都会有房屋因地面液化而发生沉降或倾斜等损坏的报道。为了防止这些破坏，提出了一些液化对策，并证明了这些效果。但是，对于已经建成的房屋，以及减轻和抑制房屋液化破坏的方法，其效果的验证还不够。因此，本研究借由1G模型振动台试验及简化分析，以确认既有住宅地面人工排水管对策之效果，并建立其设计方法。其结果是，可以从模型试验中确认对策的破坏抑制效果，并通过数值分析，可以再现液化对策的相对房屋沉降抑制效果。
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.
