针对两种典型土体,粉砂和粉质黏土,着重讨论水泥土渗透系数随水泥掺量和养护龄期的变化关系,研究结果表明,对于粉砂,在10%~25%水泥掺量范围内,随着水泥掺量的增加水泥土的渗透系数逐渐减小.在养护龄期28d~60d的过程中,水泥土的渗透系数有明显减小,60d后水泥土的渗透系数变化已经不再明显.而对于粉质黏土,达到10%的水泥掺量和28d的养护龄期后,水泥土的渗透系数变化均已经不再明显.

The article mainly discussed the relationship of cement soil permeability coefficient with cement content and curing age for two kinds of typical soil,silt and silty clay. The results showed that the permeability coefficient of cement soil gradually decreases with the increase of cement content in the range of 10%~25% cement content. In the process of 28d~60d curing age,the permeability coefficient of cement soil was obviously decreased,after 60d the change of permeability coefficient of cement soil was no longer obvious. But it was no longer obvious when cement content reached 10% and after 28d curing age for silty clay.
