水泥土抗渗性能室内试验研究

Study on anti-permeability performance of soil-cement

目前,水泥土在工程中已得到广泛应用,也有很多关于水泥土力学性质的研究成果,但水泥土抗渗性能方面的研究相对较少。本文对上海地区淤泥质粘土水泥土进行室内渗透性试验研究,探讨了水泥土渗透系数受水泥掺入量的影响程度,并认为水泥土渗透系数受龄期影响较小。对试验数据做回归分析,得到水泥土渗透系数与水泥掺入量的定量关系。

Soil-cement technique has been widely used in civil engineering.A great many studies on mechanical feature of soil-cement were made,but there are few studying the anti-permeability feature of soil-cement.This paper studies the effects of cement content on permeability coefficient of soil-cement;and the quantitative relationship between them is concluded based on regression analysis.The result also shows that the age of soil-cement has contributed little to permeability.
