Hydraulic Conductivity of Compacted Fine-Grained Soils and Its Significance in Hydraulic Structures
The permeability behavior of compacted fine-grained soils is of great practical importance. The permeability behavior of compacted kaolinitic soils and montmorillonite soils has been carried out for the present experimental study, for the IS light and heavy compaction energy levels. One-dimensional consolidation experiment has been carried out corresponding to 0.95ρdmax on dry side of optimum, optimum, and 0.95ρdmax wet of optimum moisture content, for the pressure ranging from 6.25 to 1600 kPa, and the consolidation parameters like Cv and mv were compared for different energy levels and liquid limit. The soils compacted on dry side of optimum are exhibiting higher values of K than wet of optimum condition. Due to the influence of fabric on consolidation process, kaolinitic soils are having higher K than that of montmorillonitic soils, irrespective of the clay mineralogical composition. IS heavy compaction energy level gives lower value of K than light compaction energy level. The magnitude of computed K from the conventional equation is always lesser than the experimental one, and also, it was influenced by the clay mineralogical composition, for both low and high liquid limit soils.
