赤泥掺入对水泥土渗透系数的影响

Influence of red mud on permeability coefficient of loess solidified by cement

为了研究赤泥的掺入对水泥土渗透系数的影响,通过将不同量的赤泥掺入到水泥土中,进行不同渗透压和不同龄期下的水泥土渗透试验,绘制赤泥掺入量、渗透压、养护龄期与水泥土渗透系数的相互关系曲线,进而分析赤泥的掺入对水泥土渗透系数的影响。试验研究结果表明:赤泥的掺入极大地减小水泥土的渗透系数,有助于提高水泥土的抗渗性;随着渗透压和养护龄期的增加,不同赤泥掺入量的水泥土的渗透系数变化趋势一致,基本保持稳定。

In order to study the effect of red mud on the permeability coefficient of cement soil,different amounts of red mud were added to cement soil. The permeability coefficient of the solidified soil was tested under the condition of different permeable pressures and curing time. According to the test,the relationship between permeability coefficient,red mud,permeable pressures and curing time was analyzed,and then the effect of red mud on the permeability coefficient of cement soil was analyzed. The test showed that the incorporation of red mud would greatly reduce the permeability coefficient of stabilized soil and help improve the impermeability of the soil; that,with the increase of permeable pressure and curing time,the permeability coefficient of loess solidified by different proportions of red mud and cement basically has the same change trend.
