An Analysis of Bearing Capacity of Footings on Dense Sand Using Bolton Model

Abstract

In this research, the soil failure criterion of Bolton's model is used to determine the bearing capacity of footings on dense sand soils. The strip foundations were studied under a plane strain condition. The analysis used the upper and lower bounds of the finite element limit analysis (FELA). Bolton's model can be used to investigate the relationship between strength and dilatancy to understand the behavior of dense sand and strip foundations. Additionally, in order to verify this study, the present results are compared to several past studies. and the ANN model, which is similar to the basic concept of the human nervous system, was used to examine the relationship between the input data and the output data in order to predict the problem's bearing capacity. The accuracy of using the ANN model was measured using three statistical measures, namely the coefficient of determination (R2), mean absolute error (MAE), and root mean square error (RMSE), with values of 0.99, 152.16, and 203.92, respectively. Predicting the bearing capacity of a foundation using the ANN model generates results that are usually similar to the bearing capacity of a foundation using the FELA approach.
