MODELLING OF PILE LOAD TEST IN DIFFERENT SOIL MODELS WITH FINITE ELEMENT METHOD AND COMPARISON WITH FIELD TEST RESULTS

In this study, static pile load test was conducted in the planned site in order to evaluate the results and redesign the project in a pile foundation application that were designed for 8-storey residential project constructed in Ceyhan-Adana by TOKI (Provision of Social Housing in Turkey). The design load of the single pile was corrected according to the results obtained from the static pile load test. The static pile load test was modelled in the concept of this study with using 2D-FEM analysis and two common soil models for a clayey soil under saturated soil condition and their results were compared with field test results. Plaxis-2D commercial software package program that is commonly used by geotechnical engineers in all over the world was used for this study. The selected soil models in order to propose the pile load test in FEM analysis are Hardening Soil Model and Mohr Coulomb soil model. When field test results and numerical models’ results are compared with each other, it was observed that Hardening Soil Model gives more accurate results than Mohr Coulomb soil model for this study. As a result that the ability of static pile load test modelling with 2D-FEM analysis were presented with comparison results in this study
