Abstract

 

In the present study, 0, 10, 20, 30, 40, 50 and 60 g. Sodium hexametaphosphate (NaPO3) suspensions were prepared for hydrometer tests. After the completion of the tests, the particle diameters of the soil were calculated for each hydrometer reading at time intervals of (0, 1, 2, 5, 10, 15, 30, 60, 120 and 260 min). A model was developed using an adaptive neuro-fuzzy inference system (ANFIS) to predict the particle diameter of soil for different cases without the need for a test. The quantities of the NaPO3 and the hydrometer reading times were used as inputs in the model.  Test results and predicted outcomes were compared and high correlations were obtained.

 

Key words: Soil mechanics, particle diameters, hydrometer test, ANFIS.
