Abstract
Pile driving is one of the pile construction methods to install prefabricated concrete piles using special tools. Driving method and its process is one of the most important aspects of implementation of this pile, so that the lack of sufficient accuracy to this problem, in addition to reducing operation efficiency, affects the surrounding environment and soil. In this paper, the behavior of cylindrical and tapered hollow piles were investigated with real tests and numerical analyses using FLAC3D software. The efficacy of pile geometry such as cylindrical and tapered hollow piles is analyzed in pile driving under hammer impact. Pile T is fully tapered hollow pile, and pile C is cylindrical one. All piles made by steel have the same length (Lp = 250 cm) and volume. Their properties are in Table (1). The single acting hammer with a 300 kg weight falling through a distance of 1 m is used to install all piles to the embedded length of 0.5 m to 2 m. The pile driver is made by different parts such as mounting frame, hammer and electric motor for lifting the ram to the selected falling height, and the hammerhead falling to induce an impact on the hammer components. The sand deposit was located in Vardavard-Tehran with maximum specific weight (gd,max), 2.16 kg/cm3 and relative density of about 93%.
