【摘要】 介绍和分析了粉煤灰粉喷桩软土地基加固的机理 ,并通过对粉煤灰加固土配合比及抗压强度试验 ,确定了粉煤灰粉喷桩软基加固中粉煤灰的掺入量。从物理性质与抗压强度方面将粉煤灰加固土与水泥加固土进行比较 ,证明粉煤灰作为软基加固的胶结材料 ,从加固效果及经济上均优于水泥。经过实际工程应用 ,该方法可适用于大范围的软土地基加固更多还原

【Abstract】 The paper introduces and analyzes the mechanism of soft base consolidation with fly ash spraying piling. By the test of mixing ratio and compressive strength, the proportion of fly ash to soft soil base is therefore determined. It also has the comparison between fly ash earth and cement earth in physical quality and compression strength, and it is testified that fly ash, being as cementing material in soft soil base, is finer than cement both in its effect and cost. After the practical application, this method can be applied to the consolidation of soft soil base in large scale.更多还原
