Test results show that:1) the largest seismic response is in pile head due to the effect of inertia;2) Seismic response is different in various embedded depth,with the smallest in bottom and the larger in central than in bottom and top;3) Foam boundary affects the acceleration response of particles inside soil with less response than the case with no foam boundary. Therefore,foam boundary is required in shaking table test of pile-soil interaction research %K 振动台试验 钢箱边界效应 加速度响应 泡沫边界< %K br> %K shaking table test steel box boundary effect acceleration foam boundary %U http://xbzrb.fzu.edu.cn/ch/reader/view_abstract.aspx?file_no=201604009&flag=1
