Abstract
Pile jacking process can lead to high bearing capacity, stiff base response but sometimes excessive installation resistance. However, it limited by jack capacity and negative shaft resistance. To overcome some of the above problems and to improve the pile performance, rotary jacking of the pile is used. It can alleviate installation problems and bearing capacity is activated during subsequent loading. Therefore, the objective of this research is to investigate the behavior of pile using this new innovative technique. A 25 mm circular fabricated steel pile was used for the experiments The experiments were done in the laboratory using a large container filled with silica sand, and the rotary and jacking method was tested with few series of cases. Results show that this new method of pile installation is successfully obtained and acceptable. This new method of pile installation is an innovative method to be used for the future in the construction industry.
