摘要
文中以某高层建筑基坑工程为例,对排桩+内支撑复合支护体系在深基坑中的应用进行分析.结果表明,排桩+内支撑复合支护体系整体施工效果达标,地表沉降控制在 12 mm内,支撑结构变形仅 5 mm,地下水位波动不超过 5 m,有效解决了复杂地质条件下基坑工程的施工问题,为深基坑施工提供了高效可行的解决方案.
Abstract
This paper takes a high-rise building foundation pit project as an example to analyze the application of pile row + internal support composite support system in deep foundation pit.The practical results show that the overall construction effect of the pile row + internal support composite support system of the project is up to standard,the surface settlement is controlled within 12 mm,the deformation of the supporting structure is only 5 mm,and the fluctuation of the groundwater level is not more than 5m.It effectively solves the construction challenges of foundation pit engineering under complex geological conditions,and provides a stable and efficient solution for deep foundation pit construction.
