Estimation of Ultimate Bearing Capacity of Soil for Shallow Foundation
Evaluation of ultimate bearing capacity is a tedious process, as the determination of shear strength parameters within the underlying soil structure is a difficult task. The purpose of current research work was to arrive at an alternative way for calculating ultimate bearing capacity by thoroughly considering soil properties like density, specific gravity and grain size distribution. Soil samples were collected from different construction sites of South Goa at 1.5 m depth from the ground level. Numerous tests like core cutter, moisture content, specific gravity, direct shear, sieve analysis and pipette analysis were conducted to determine the soil properties. Using the results of direct shear test (c and ɸ values), ultimate bearing capacities were calculated as per Terzaghi, Hansen, Meyerhof, Vesic and code IS: 6403-1981 methods for square footing of 2 m × 2 m. The softwares like SoFA and OptumG2 were also used to calculate ultimate bearing capacities. Various correlation equations were arrived between different soil properties and ultimate bearing capacity using multiple regression technique. The softwares used to arrive at a regression equation were IBM SPSS Statistics 24 and Minitab. Prediction accuracies were evaluated using coefficient of determination, root mean square error and mean error between the measured and the predicted values.
