CFG桩复合地基受力沉降变形及应用研究

Study on Deformation and Application of CFG Pile Composite Foundation

通常在对建筑结构进行设计时,所采用的深基坑形式为条形基础或箱形基础等形式,然而一旦发生基础承载力与沉降要求不相适应时,则就会采用复合地基方式。在应用复合地基时,因CFG桩有着成本较低,绿色环保和技术完善的特点,且可有效缓解地基沉降变形,故被广泛的应用。针对CFG桩复合地基受力沉降变形及应用进行了分析与探讨。

Usually, when we design the building structure, we adopt the form of deep foundation pit, such as strip foundation or box foundation.But once the bearing capacity and the settlement requirements are not suitable, the composite foundation will be adopted.In the application of composite foundation, CFG piles are widely applied because of their low cost, environmental protection and perfect technology, and they can effectively relieve the settlement and deformation of foundations.In this paper, the deformation and application of the CFG pile composite foundation are analyzed and discussed.
