Experimental Study of the Effect of a Compacted Lime-Treated Loess on Its Hydraulic Conductivity

In this paper, the influence of the lime content on the compaction characteristics and saturated hydraulic conductivity of lime-treated loess is studied experimentally. The test results reveal that as the maximum dry density drmax\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$ \left({d}_{r_{\mathrm{max}}}\right) $$\end{document} decreases, the corresponding value of optimum moisture increases with increasing lime content, and the relationship between lime content and drmax\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$ \left({d}_{r_{\mathrm{max}}}\right) $$\end{document} is nonlinear. On a semi-logarithmic scale, the relationship between the void ratio and the saturated hydraulic conductivity of the lime-treated soils is a cluster of parallel lines with intercepts that are related to the lime content.
