COMPARATIVE ANALYSIS OF NUMERICAL MODELING AND STATIC PILE LOAD TEST RESULTS FOR CFA PILES

The goal of this paper is a comparative assessment of results obtained from the field static pile load test and simulated numerical analysis. Plaxis 3D Foundation software was used to simulate the field static pile test for numerical analysis. Results of this study demonstrate the comparison of load-settlement curves obtained from field static pile test and numerical analysis of CFA pile. As a result of field static pile load test, the bearing capacity of the pile was determined. Moreover, results of residual settlement after unloading in case of the field test and numerical analysis were demonstrated. As a result of the load-settlement curve, numerical analysis with Plaxis 3D software is applicable for pile design with sufficient accuracy. The study emphasizes the importance of validating CFA pile behavior through both empirical and computational approaches in challenging geotechnical conditions. This dual- method approach helps improve the accuracy of pile foundation design and ensures better reliability of structural performance. The correlation between measured and simulated results allows engineers to verify modeling assumptions and boundary conditions. Additionally, this approach offers a cost-effective solution in large-scale construction projects where field testing every pile is impractical. Ultimately, the integration of field testing with advanced numerical modeling supports optimization in foundation engineering and contributes to safer and more efficient construction practices.
