| 摘 要： | 为研究永久性土钉支护结构体系的抗震性能,设计并完成了土钉支护边坡1∶12比尺的振动台试验,研究了在不同支护条件(如土钉倾角、土钉长度、土钉间距等)下边坡的动力反应特征和规律.结果表明:土钉支护边坡在振动过程中,最大变形出现在边坡坡腹位置,坡趾处的位移较小;土钉支护最大作用带位于土钉支护区的中前部,呈折线形;最下面一排土钉发生最大应变的位置靠近坡面;边坡土体中部和下部的加速度放大系数较小而且比较接近,边坡上部土体的加速度放大系数较大.

| Abstract: | The aseismic behavior of permanent soil-nail supporting system is investigated by shaking table tests with a scale factor of 1/12.During the tests,dynamic characteristics and rules of the slope are investigated with different supporting conditions,such as nail inclination,nail length and nail space.In vibration condition,the lateral displacements mainly occur at the abdomen of the slope,and the displacements at the crest and foot are relatively small.The shape of maximal function belt is polygonal-shape and... |
