This paper outlines the behavior of large diameter bored piles in calcareous cemented sand in the state of Kuwait. This objective was achieved by investigating the characteristics of calcareous cemented sand in Kuwait, the reported capacities of large diameter bored piles (Diameter 0.6m to1.5m), estimation of pile capacity from pile load tests up to and/or near failure. Calibration of numerical models, constitutive laws and the corresponding soil parameters is an essential design stage to transfer the gained data from single pile load test to the design of the pile foundation. The ability of a Hardening Soil (H-S) model to represent the stress-strain behavior of calcareous cemented sand was checked and implemented to backcalculate the measured load-settlement performance of large diameter bored piles in calcareous cemented sand. The results show that the H-S model can reasonably represent the behavior of large diameter bored piles in calcareous cemented sand.
