摘要
水泥粉煤灰碎石桩(CFG桩)具有:对不良地基加固效果良好;适用范围广泛;桩体不需要钢筋笼骨架;采用粉煤灰替代部分水泥降低水泥使用量且回收粉煤灰节能环保降低工程造价;成桩方法多样,施工机械选择范围大等一系列优点。因此被广泛的应用于建筑工程地基处理当中。文章主要介绍了在沼泽地区淤泥质土且高地下水位等不良地质条件的高层建筑物地基处理当中,应用水泥粉煤灰碎石桩(CFG桩)的过程和效果。
Cement fly ash gravel pile(CFG pile)has:good reinforcement effect on bad foundation;wide range of application;pile body does not require reinforced cage framework;using fly ash to replace part of cement reduces cement usage and recycles fly ash energy saving and environmental protection reduce project cost;a variety of pile formation methods,a wide range of construction machinery selection and other advantages.Therefore,it is widely used in foundation treatment of construction projects.This paper mainly introduces the process and effect of applying cement fly ash crushed stone pile(CFG pile)in the foundation treatment of high-rise buildings with muddy soil and high groundwater level in swamp areas.
