Influence of Fine Fraction on Shear Parameters and Consolidation Behavior of Tropical Residual Soil


Objectives: Tropical residual soils are widely available in the southern part of India and the construction in this type of soils more challenge issue to the geotechnical engineers to design the structure in the settlement criteria. Analysis: Tropical residual soils are in general are regarded as multi component, polyphase, and particulate system with compositional and/ or structural discontinuities. Both index and engineering properties of natural soils primarily depend on mineralogy and percentage of fine fraction. Findings: In this paper, eight soil samples are considered for to obtain the influence of the fine fraction on shear parameters and consolidation behavior of tropical residual soils in Tirupati region. Shear strength tests and one-dimensional compression tests have been conducted apart from the classification and identification tests. Application/ Improvement: Based on the experimental test results and analysis, it has been found that the percentage fine fraction has a greater significant influence on engineering properties like cohesion, angle of internal friction and compression index of tropical residual soils.
