无砂混凝土碎石桩加固饱和软粘土地基的方法

提出了一种相对经济的半刚性桩一无砂混凝土碎石桩复合地基,并给出了具体设计计算方法及设计参数,该桩克服了散体桩在饱和软粘土中侧限不足的缺陷,提高了复合地基的承载力,实际工程应用表明,饱和软粘土地基经济该桩加固后,承载力得到显著提高,满足了中,小型工程的设计需要。

A METHOD TO STRENTEN SATURATION SOFT CLAYEY SOIL FOUNDATION BY SANDLESS CONCRETE AND STONE COLUMN

In this paper,we propose a semio rigid column,i.e.sandless concrete and stone column composite foundation.A calculation method is also given for the design reference.Comparing with dispersive piles,the proposed column can effectively improve the side-restricted capability in saturation soft clayey soil.The practice application shows that the column has obviously stressed saturation soft calyey soil foundation.It can meet the designing needs for small or middle-sized engineering.
