粉土及稳定粉土的基本特性与工程应用研究

The study on properties and engineering application of silt and stabilized silt

结合陇海铁路郑(州)徐(州)段电气化改造工程,对粉土的基本特性进行了研究总结,并对水泥、石灰及二灰稳定粉土的工程特性进行了分析对比,得出三种掺合料可以改良粉土工程性质,但改良效果程度不同,水泥比石灰的改良效果好,在掺合比相同的条件下,二灰比石灰的改良效果也要好的结论。

Combining the electrification project of Zheng-Xu section of Longhai railway, the properties of silt are studied, and the engineering behaviors of stabilized silts which are made by adding cement, lime and lime and fly ash into the silts, are analyzed and compared. The results show that the three admixtures can improve the engineering characteristics of silt, but the improved effectiveness degrees are different. Under the same mixture ratio, the improved effectiveness of cement and lime and fly ash is better than lime in stabilized silts.
