水泥土渗透系数试验模拟分析

Simulation and Analysis of Cement-Soil Permeability Coefficient Test

摘要:

为更好地指导工程实践,研究不同水泥掺入比、不同养护龄期和不同种类的土对水泥土渗透系数的影响, 进行了水泥土渗透性室内试验。选取3种黏粒含量不同的细粒土和普通硅酸盐水泥,选择不同水泥掺入比12%、16%、 20%,采用分层击实法制备水泥土试件,分别进行7d、28 d、90 d 标准养护,进行渗透试验,并分析渗透系数在不同条件下的变化规律。

Abstract:

In order to better guide engineering practice, indoor tests on cement-soil permeability were carried out to study the effects of different cement mixing ratios, different curing ages, and different types of soil on the permeability coefficient of cement-soil. Three types of fine-grained soils with different clay particle contents and ordinary Portland cement were selected. Different cement mixing ratios of 12%, 16%, and 20% were adopted, and the layered compaction method was used to prepare cement-soil specimens. The specimens were subjected to standard curing for 7 days, 28 days, and 90 days respectively, and permeability tests were conducted to analyze the variation law of permeability coefficient under different conditions.
