摘要
在某软弱地层上进行基坑开挖时,软土流动将坑内工程桩挤偏。为加固偏位群桩基础,保证桩基础安全、有效地承担上部结构荷载,采用锚杆静压桩并采取桩基逆作法对偏位群桩基础进行了补强,补桩过程中,实时观测基础沉降,以调整施工次序。
When excavation was being carried out in a soft foundation pit, the flows of soft soil squeezed away the engineering piles in the pit. In order to reinforce the deflected pile foundation and make it bear substructure load safely and effectively, statically-driven anchor piles by inverse construction were used to treat the destabilized pile foundation. Real-time monitoring of the foundation settlement was applied in the course of pile reinforcing construction ,so as to adjust the construction sequence timely,
