Shear strength is an important mechanical property of the soils. Mohr Columb strength model is widely used to mathematically define the shear strength of the soil, which is also of prime importance for the constitutive modelling of the soil. Shear strength of the granular soils can be determined from the angle of internal friction, which is a model parameter. To determine the angle of internal friction, direct shear tests are performed. Such tests are tedious, laborious and require expertise to conduct them. Thus, it is desirable to develop a quick method for the prediction of the angle of internal friction. One such method of quick prediction is to develop the prediction models, correlating quickly assessable properties with tediously determined parameters. In the present study, the authors established the relationship between the grain size of soil particles and the angle of internal friction. Finally, prediction models are established, using grain percentage of sand and percentage of fines as variables. The validity of developed models is also checked on a separate set of soil samples. The prediction models are found to be valid within the ceratin bounds. [ABSTRACT FROM AUTHOR] |
