CFG桩复合地基是在碎石桩加固地基法的基础上发展起来的一种地基处理技术。由于CFG桩改善了碎石桩的刚性,使其不仅能很好地发挥全桩的侧阻作用,同时也能很好地发挥其端阻作用。因此,得以广泛采用,并取得良好的经济和社会效益。本文将对CFG桩的施工工艺进行探讨。 CFG pile composite foundation is a foundation treatment technology developed on the basis of gravel pile foundation method. The CFG pile improves the rigidity of the pile, so that it can not only fully exert the side-blocking effect of the pile but also exert its end-resistance function well. Therefore, it has been widely adopted and has achieved good economic and social benefits. This article will discuss the CFG pile construction process.
