大直径圆形深基坑基底回弹问题研究

Researches on heave of circular deep foundation pits with super diameters

基坑回弹问题是一个非常复杂的课题,涉及的影响因素非常多,圆形基坑的回弹不同于其它形状基坑的回弹。本文结合上海环球金融中心等工程实例分析了影响圆形基坑的一些因素,得出了一些对圆形基坑基底回弹研究与设计施工非常有价值的结论。

The problem about deep foundation pit heave is very complicated, and it relates with a lot of factors. The rebound of circular pits is defferent from that of other forms. Some valuable conclusions were drawn for the circular excavation research, design and construction combined with the deep excavation project of Shanghai World Financial Center and so on.
