Prediction of bearing capacity of driven piles for Basrah governatore using SPT and MATLAB

Abstract Based on the results of standard penetration tests (SPTs) conducted in Al-Basrah governorate, this research aims to present thematic maps and equations for estimating bearing capacity driven piles having several lengths. The work includes drilling 135 boreholes a depth 10 m below existing ground level three (SPT) at depths 1.5, 6, 9.5 were each borehole. MATLAB software corrected SPT values used determine Al-Basrah. Several-order interpolation polynomials are suggested estimate piles, but first-order polynomial is considered most straightforward. Furthermore, root means squared error (RMSE) all roughly same. production demonstrates variation over entire territory governorate correlation with different depths. statistical showed that there good agreement those obtained from data. When compared observed SPT, allowable ranged (−3 +38)%. main study 30% between calculated estimated lengths 95% confidence interval.
