Influence Of Induced Stresses On Geotechnical Characteristics Of Sand
Generally before the construction of any construction project the sub soil investigations were carried out to evaluate the various geotechnical properties of soil like shear strength, permeability etc. The sustainability of the projects largely depend upon the true prediction of the behaviour of the soil in long term and short term. However due to the application of external loads the stress induced on the soil increased and its effect remain high at shallow depths. This may cause the breaking of the soil particles particularly for coarse soils like gravel and sand. This paper demonstrates the influence of induced stresses on the geotechnical characteristics of sand. The static normal stresses were induced in the range of 5-20 MPA with help of Universal Testing Machine (UTM). It is seen that with increase of static stresses the breaking of sand particles occurred. This possibly results in the decrease of permeability and shearing strength.
