| 摘 要： | 广州新电视塔总高610m,该电视塔外筒24根钢管混凝土斜柱直接落在大直径桩上,桩顶通过环梁连成整体;采用考虑桩、筏板与基岩共同作用的有限元分析方法,计算基础沉降变形;通过在桩内进行的基岩侧摩阻力试验,验证了规范的经验取值,确定了桩基础的抗拔承载力,较好地解决了大直径、大抗拔力桩的检测问题。

| Abstract: | Guangzhou New TV Tower has a total height of 610 m.Twenty-four concrete-filled steel tube inclined columns of the TV Tower are planted on large diameter piles which are linked together through circular beams on the top.By using finite element analysis method,the interaction of piles,raft and bedrock was considered to calculate the deformation and subsidence of the foundation.By the test of the friction along the bedrock side in the pile,the empirical estimation of the existing specifications was verified,th... |
