“…The latter statement is based on the fact that soil conditions (e.g. large soil reaction) can affect the power consumption, which occurs in vibratory driving due to the vibrator-pile-soil interaction [23] and can even lead to pile refusal [24]. Further, a drop in torsional power consumption is visible for GDP 2 between 50 s to 100 s (4 meters penetration in Fig.…”

“…During impact installation, the pile is pushed into the soil using a falling mass. This method more likely causes damage to the pile such as pile buckling [3,4]. In contrast, the vibratory driving method is a cheaper, faster, and less noisy alternative where the pile is driven using an axial periodic motion.…”

“…In the case of non-cohesive soils, the resulting vibration due to the motion forms two different zones. In the zone near the pile shaft, the surrounding soil is loosened, which reduces both the soil resistance and its friction with the pile, making the penetration easier [3]. This small region is commonly referred to as a liquefaction zone.…”

Pipe-piles are installed using impact or vibratory driving which influences the soil in different ways including the void ratio and stress distribution. Such complex problems are hard to investigate on the field as well as using numerical methods. Here, a sophisticated numerical approach is employed to evaluate the soil behavior during pile installation. Also, a sensitivity analysis on the frequency and the impact duration is done for vibratory and impact driving, respectively. The investigation includes the required force of the pile installation, pile penetration behavior, plugging formation inside the pile, and the change of the soil state including the change in the horizontal stress and density around the pile during the installation. Results of the numerical model show several advantages of vibratory driving over impact driving in the dense sand including, reaching the designated depth using less momentum and work as well as more soil compaction.

“…Conventionally, impact or vibratory driving is applied. Compared to impact driving, the vibratory driving produces less noise level, induce less damage to the pile, and offers a significantly higher penetration rates (Holeyman and Whenham 2017;Rausche 2002). In this study, the effects of vibratory driving on the soil are investigated by varying the installation frequency.…”

In offshore geotechnics, tubular piles are commonly used as the foundation system. Such piles are installed using vibratory or impact driving. The choice of the proper loading configuration plays an important role in the driving performance, especially in reaching the desired penetration depth. Numerical evaluation of such processes involves handling large material deformation, making it hard for the classical numerical methods to reach a reliable result after significant deformation. In addition, in case of the dynamic cyclic loading, the soil exhibits complex behavior which emphasizes the role of a suitable soil constitutive equation. In this study, a numerical model is developed and utilized to evaluate the effects of the frequency in the vibratory installation of tubular piles on the neighboring soil. The numerical model employs the robust Multi-Material Arbitrary Lagrangian-Eulerian (MMALE) method in conjunction with an advanced material model formulation based on the hypoplasticity concept, and is validated against an experiment done at TU Berlin. Subsequently, a parametric study is performed by applying six different frequencies between 12 and 30 Hz to the dynamic load. The resulting penetration depth, void ratio and the lateral stress distribution in the soil are compared and evaluated. It is concluded that an optimum frequency must be determined to reach the maximum penetration depth by using the same load magnitudes.
