摘要
水泥粉煤灰碎石桩是近年来发展起来的理软弱地基的一种新方法。其特点是:改变桩长、桩径、桩距等设计参数,可以使承载力在较大范围内调整;有较高的承载力,承载力提高幅度在250%～300%,对软土地基承载力提高更大;沉降量小、变形稳定快;工艺性好;由于大量采用粉煤灰,桩体材料具有良好的流动性与和易性,灌注方便,易于控制施工质量;可节约大量水泥、钢材,利用工业废料,消耗大量粉煤灰,降低工程费用,与灌注桩和预制桩加固相比,可节省投资30%～50%,文章介绍水泥粉灰碎石桩复合地基技术应用情况。
CFG Plie is a new way to deal with soft foundation in recent years. Its characteristics is that the bearing capacity can be adjusted in large range, bearing capacity increases greatly in soft foundation, the construction quality control becomes easy, and the resource and cost can be reduced greatly. In this paper the application of CFG compound foundation is introduced.
