Abstract — In most standards and codes of practice, the piles specifications and recommendations are stated for short piles which has a maximum depth range between 18.0 to 20.0 m [708.66 to 787.40 in]. In addition, the theoretical equations for pile design, charts and different soil parameters are based on old practical studies of short piles behavior. In this research, a comparison was conducted between the theoretical pile compression capacity, the practical pile compression capacity which is derived from the results of pile’s static load test and the numerical pile capacity by using PLAXIS 2D software.

The study covered one case of bored piles constructed in Dubai, that pile depth is equal to 34 m [1338.58 in]. Moreover, a finite element model done by using PLAXIS 2D software, to judge between the practical and theoretical pile capacities. As a result of the research, the theoretical compression pile capacity was almost 70% of the practical and numerical pile capacity with the same specifications.
