“…Ramshaw et al [24] and Khoubani et al [25] proposed an axisymmetric model based on finite/infinite elements to simulate the pile-ground system. A similar modeling technique, but this time using artificial boundaries based on a gradual increase in soil damping to simulate the Sommerfeld's condition, was presented by Homayoun Rooz and Hamidi [26]. Following a similar strategy for the treatment of artificial boundaries, Sofiste et al [27] recently proposed a computational model based on an explicit time-domain analysis.…”

The automatization of construction activities, which aims to reduce the time and cost of constructions, makes impact pile driving an interesting technique. However, these activities in urban areas can generate excessive vibrations and interfere with people and structures in the vicinity. With that in mind, predicting the expected vibration levels during the project design stage is essential. Different methodologies can be employed in this task, from empirical approaches to detailed and complex numerical formulations. This paper intends to present an overview of the empirical methods and the main physics of the problem from a numerical point of view. The results obtained are then compared with experimental vibration data reported in the literature in order to discuss the adequacy of empirical and numerical methodologies in predicting ground-borne vibrations induced by impact pile driving.

“…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.…”

Driven Pile Effects on Nearby Cylindrical and Semi-Tapered Pile in Sandy Clay

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°.
