“…They were conferring to the Technical Manual TM 3-34.22 (U.S. Army 2013). Farshi and Hamidi [16] proved that an augmentation in PPV conducted an upsurge friction coefficient principally near to the pile axis. Therefore, the friction coefficient reduction by adopting a steel pile rather than a concrete pile induced attenuation of ground vibrations.…”

“…Therefore, the friction coefficient reduction by adopting a steel pile rather than a concrete pile induced attenuation of ground vibrations. The pile-soil friction coefficient was taken as 0.35 in this paper, according to [15,16,48].…”

“…The boundary element was proposed by [47] to capture the soil behavior. Other papers used artificial boundaries to absorb the wave deriving from the driven pile [15,16,48,52]. A regular augmentation of the damping was adopted for absorbing the wave and its limited the errors before model verification [53].…”

“…Zhang and Tao evaluated the limit of the Rayleigh damping from 2.4-15.4% for clays and from 1.5-17.5% for sands. The soil damping was taken as 7% as provided by [15,16] for a similar soil layer. The depth of the soil was seized large enough to allow the natural damping of the waves at the bottom boundary.…”

A pile foundation is commonly adopted for transferring superstructure loads into the ground in weaker soil. They diminish the settlement of the infrastructure and augment the soil-bearing capacity. This paper emphases the pile-driving effect on an existing adjacent cylindrical and semi-tapered pile. Driving a three-dimensional pile into the ground is fruitfully accomplished by combining the arbitrary Lagrangian–Eulerian (ALE) adaptive mesh and element deletion methods without adopting any assumptions that would simplify the simulation. Axial forces, bending moment, and lateral displacement were studied in the neighboring already-installed pile. An investigation was made into some factors affecting the forces and bending moment, such as pile spacing and the shape of the already-installed pile (cylindrical, tapered, or semi-tapered). An important response was observed in the impact of the driven pile on the nearby existing one, the bending moment and axial forces were not negligible, and when the pile was loaded, it was recommended to consider the coupling effect. Moreover, the adjacent semi-tapered pile was subjected to less axial and lateral movement than the cylindrical one with the same length and volume for taper angles smaller than 1.0°, and vice versa for taper angles greater than 1.4°.

“…Pile driving is a complex dynamic process, and as such, there have been numerous studies on various aspects of pile driving. In the literature, there are several studies related to pile driving induced vibrations [1,[5][6][7][8][9][10][11][12][13][14][15][16][17]. In these studies, pile driving modeling and/or particle velocity or acceleration effects induced by pile driving have been presented.…”

The pile method, applied in the foundational operations of construction to enhance soil bearing capacity, is utilized in locations where there is insufficient soil support. Its purpose is to reinforce the foundation and improve soil stability before constructing a structure. In this study, vibrations occurring during the application of Vibrex-type piles for foundation reinforcement in a construction project located in the Konak district of Izmir Province were measured at various distances from the measurement points. The study further explored the influence of pile application on soil stability, considering the geomechanical properties of the site's soil structure. The resulting analysis from the study's graph indicates that stress and vibration velocity remain at optimal levels, suggesting favorable working conditions.
