摘要
进行超高建筑深基坑施工时,采用了排桩+预应力锚索的基坑支护体系,其具有稳定性好,安全性能高和承受土体荷载能力强的特点,能将基坑的变形控制在允许的范围内,确保了本项目超高建筑软弱地质深基坑地下结构施工的安全。
In the construction of deep foundation pits for super-high buildings,the foundation pit support system of row piles+prestressed anchor cables is used,which has the characteristics of good stability,high safety performance and strong soil load bearing capacity.The deformation of the pit is controlled within the allowable range,which ensures the safety of the construction of the underground structure of the deep foundation pit in the ultra-high building and weak geology.
