摘要
以水泥土防渗墙、基坑、堤坝等抗渗性能的安全性和耐久性为研究背景,对不同水泥掺量的水泥土进行了渗透试验,得到了不同水泥掺量的水泥土渗透系数随水泥掺量、养护龄期的变化规律。试验结果表明,水泥土渗透系数随着水泥掺量的增加而减小,随着养护龄期的增加水泥土渗透系数逐渐降低。通过回归分析,得到了水泥土渗透系数随养护龄期和水泥掺量的变化方程。
In this paper,cemented soil impervious wall,excavation,dams and other impermeability of safety and durability are adopted as the research background,the different cement content of cemented soil penetration test is performed to obtain the variation of soil permeability coefficient with different cement content and curing period. The results showed that:the permeability coefficient of cemented soil decreased with the increase of cement content and with curing period increased cemented soil permeability coefficient decreased. Finally,through regression analysis,of cemented soil permeability coefficient change equation is adopted with the conservation of age and cement content.
