深层水泥搅拌桩的设计

Design of Deep Mixed Cement Pile

结合某花园小区工程的实际地质情况,介绍了深层水泥搅拌桩加固软土地基的具体设计方案,其内容包括布桩形式、单桩竖向承载力及复合地基承载力的确定以及下卧层与沉降变形的验算。指出水泥搅拌桩是对软土地基基础加固处理的一种实用方法,它不仅能很好地减小基础沉降,同时也能有效地提高软基基床的承载能力。

Combined with the geological conditions of engineering in some garden area,the concrete design project of using deep mixed cement pile in reinforcing soft soil foundation are introduced,which contain piles' layout,the determination of vertical bearing capacity of single pile and bearing capacity of composite foundation and checking calculation of settlement deforming.This method is a practical method in reinforcing soft soil foundation.It not only reduces the foundation sinks to decline but also enhance the bearing capacity of soft soil roadbed.
