| 摘 要： | 设计并完成了刚性桩复合地基1∶10比尺的振动台试验。对刚性桩复合地基的抗震性能、桩土变形特性、上部结构的影响、柔性容器的效果等问题进行了研究讨论。结果表明,刚性桩复合地基具有良好的抗震性能,上部结构特性对桩身变形的影响不大,桩身的运动主要受自由场运动的控制,柔性容器能够较好的解决模型试验的边界问题。

| Abstract: | The anti-seismic behavior of composite foundation with rigid pile was studied by a shaking table test with the scale factor of 1/10.The earthquake response of composite foundation with rigid piles,the deformation behavior of piles and soil,the influence of superstructure,and the effect of the flexible wall container,etc.were discussed.It was found that,the composite foundation with rigid piles had a good anti-seismic performance,the influence of superstructure to the deformation of piles was not noticeable,the movement of piles was mainly controlled by the free field response,and the boundary effect of model test was properly treated by the flexible wall container. |
