Abstract: The accurate estimation of the pile axial capacity is a very difficult task until present time, especially for displacement piles. This thesis is dedicated to address same factors in numerical modeling of single pile behavior and the change of soil stress state during installation and subsequent loading, in order to improve the accuracy of the design of single axially loaded pile. Firstly, the effects of different constitutive soil models on modeling pile behavior were investigated. Then, the improved numerical procedure that simulates installation effects based on simple cavity expansion theory was proposed and a series of full scale pile load tests was conducted to validate the proposed numerical procedure. Last, a detailed numerical study was carried out to study the effect of negative skin friction on pile behavior and also to verify the Unified Design Method for pile foundations.
