摘要

    摘要
  • 摘要: 通过大型振动台试验研究地震荷载作用下边坡抗滑桩的抗震性能，振动台试验边坡模型放在一个长 3.7 m 、宽 1.5 m 、高 1.8 m 的模型箱中。模型与原型边坡按照尺寸相似比 1 ∶ 20 进行模型试验相似设计。经过配合比试验由标准细砂、石膏粉、滑石粉、甘油、水组成相似材料，通过控制密度 2.5 g/cm3 垒入模型箱中。模型振动台试验通过输入 3 种不同的地震波，不断加大输入地震波的幅值，通过监测桩后土压力、边坡坡面加速度和位移响应研究抗滑桩在地震作用下边坡抗震机制和地震作用桩后土压力分布形式和抗滑桩的抗震性能。试验研究为边坡抗滑桩抗震设计奠定了良好的基础。
    Abstract: The seismic behaviors of piles retaining the slopes are studied by means of large-scale shaking table tests. The model slope is installed into a model box with a length of 3.7 m, width of 1.5 m and height of 1.8 m. The sizes of model and prototype slope are designed by using the similar principles with a scale factor of 1 ∶ 20. Similar materials are made up of the standard fine sand, gypsum powder, talc powder, glycerin and water, and the specimens are reconstituted with density of 2.5 g/cm3. Three different kinds of seismic waves are input to study the dynamic response stabilizing piles by increasing the amplitude of input seismic waves. By monitoring the soil pressure after the piles, the acceleration and displacement response of the slope, the distribution of the soil pressure behind the piles and the seismic performance of the piles are studied. This research provides a good foundation for seismic design of stabilizing piles.
