摘要

摘要: 根据固化土结构的形成模型,提出了加固软土的固化剂应分别产生胶结土颗(团)粒的胶结性水化物和填充孔隙的膨胀性水化物,进而,建立了根据土样的性质指标确定固化剂组分与掺入比的计算公式。试验证明:对不同的典型土样,利用该公式计算得到的固化剂各组分的掺入比与试验得到的结果比较接近,且按本设计方法配制出的固化剂加固效果优于水泥加固的效果。

Abstract: According to the structure formation model of stabilized soil, it is proposed that the hardening agent for stabilizing soft soil should generate cementitious hydrates to bind soil particles and expanding hydrates to fill pores in the stabilized soil; calculation formulas are developed, by which dosage of components constituting hardening agent can becalculated according to characteristics of the soil. The experiment results proved that the dosages of optimal hardening agent components obtained from the experiment were close to those calculated with the formulas, and the effect of the stabilized soil stabilized by the hardening agent designed by this method were much higher than that stabilized by cement.
