Pile capacity with cone penetration test in alluvial soils

In this study; the capacities of piled foundations, which are deep foundation types, in cohesive and cohesionless soils, are obtained by using methods, tables and curves based on the CPT test developed in the literature. In the study, it was investigated how the calculation results obtained with different design methods by using cone penetration test (CPT) data differ. Analyzes were conducted for three different diameters and three different lengths in two different sections. Analyzes were made with LCPC, De Ruiter and Beringen, Schmertmann methods and LPD-CPT program, which are pile capacity calculation methods using CPT test results, and then manual and software calculation results were compared. As a result, it has been observed that large differences in results have occurred due to differences in acceptance of methods. Based on this, it is recommended to make calculations with more than one method and to include experience.
