| 摘 要： | 本文结合工程实际,建立了高层建筑上部结构-桩-土共同工作体系的动力计算模型,计算了在地震动作用下桩接头处的内力;按照标准图集中的尺寸设计了硫磺胶泥桩接头并进行了四个接头的地震模拟振动台试验和静力试验,得到了接头开裂时的弯矩和剪力。通过对比动力计算时的内力与试验时接头的抗力,评价了7度区硫磺胶泥接头的抗震能力。结合进一步的理论分析,提出了在高层建筑中使用这种接头时在抗震设计和施工方面应注意的问题。

| Abstract: | The dynamic response of sulphur-grout-joint piles is calculated by using an interaction model of soil-pile-structure, and four specimens of pile sections jointed with sulphur-grout are tested on the shaking table, then the earthquake resistant capacity of this kind of joint is estimated by comparing the calculated results with the tested results. The research results have been applied to two 25-story buildings and one 18-story building. |
