摘    要:对石灰-下蜀黄土、粉煤灰-下蜀黄土的渗透系数的主要影响因素(掺灰比、含水量)进行正交试验设计,选用双因素方差分析法分析了掺灰比、含水质量分数与渗透系数之间的关系,发现掺灰比和含水质量分数对下蜀黄土的防渗性能均有重要影响.提出了下蜀黄土防渗性能的优化设计方案,认为高含水质量分数低掺灰比的组合有利于防渗.

Abstract:By the orthogonal experiment on main influencing on permeability factors such as ratio of lime-ash and water content of lime Xiashu loess or fly-ash Xiashu loess, the relationships between such influencing factors and permeability factor were analysed by MANOVE. The result is the effect of lime and fly ash ratio and water content on permeability of Xiashu loess is significant. An optimal anti-permeable design method for Xiashu loess improvement was proposed. The favourable anti-pemeable measures is combination of high water content and low additive ratio of fly ash.
Keywords:Xiashu loess    orthogonal experiment    ratio of lime and fly ash    water content    hydraulic conductivity
