EXPERIMENTAL STUDY OF THE EFFECT OF A COMPACTED LIME-TREATED LOESS ON ITS HYDRAULIC CONDUCTIVITY

摘要

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 (dr(max)) decreases, the corresponding value of optimum moisture increases with increasing lime content, and the relationship between lime content and dr(max) 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.
