Behaviour of load-displacement curve of bored piles, which varies from region to another in delta zone of Egypt (Gharbia governorate), can be illustrated by using the results of pile load test. Numerical approaches are amongst the promising tools that can be adopted to assess the bearing capacity of bored piles. The objective of this paper is to study theoretically load-displacement behaviour of bored piles at different locations in Gharbia governorate, based on pile load test results. The study aims to perform a total survey of the bearing capacity of bored piles in delta zone of Egypt which contains cities such as Tanta, Zifta, Samannoud, Al-Mahalla Al-Kubra, Alsanta, Qu-tour, Kafr El-zayat and Bassyun. The study was carried out with the aid of numerous software such as (2D PLAXIS, version 8.2), which is depend upon elastic perfectly-plastic finite element models, as well as (All Pile, version 7; SHAFT, version 8) which are relied on (p-y) analysis curve. The results demonstrate that the ultimate pile capacity is mobilized at settlement equal to 2% of pile diameter, which is in agreement with the ECP values for small diameters.
