Because it is not possible to build structures directly on such soft ground, pile-foundation is usually adopted. If the pile foundation is damaged due to the inertial force of the structure or ground deformation during an earthquake, the structure may tilt or sink and become unusable. The failure mechanism during an earthquake, which is necessary for establishing a reasonable seismic design method for pile foundations, is not fully understood at present. With the above in mind, as part of the Ministry of Education, Culture, Sports, Science and Technology's “Special Project for Mitigating the Effects of Major Earthquakes in Major Cities”, a series of shaking table tests were conducted on pile foundations in liquefied soil to investigate the behavior of liquefied soil under seismic motion and the interaction between the soil and the structure. In this experiment, loose saturated sandy soil was used as the ground around the building, and liquefaction was induced by inputting seismic motion., データ取得:2006年, Data acquisition period : 2006, お問い合わせ:asebi@bosai.go.jp, inquiry: asebi@bosai.go.jp}, title = {水平地盤中の杭基礎の実験(液状化地盤)}, year = {2025}, yomi = {ボウサイカガクギジュツケンキュウショ} }
