“…In terms of numerical simulation, Achmus et al and Depina et al proposed an improved stiffness attenuation model to calculate the cumulative deformation of single pile under cyclic loading through secondary development, but this model ignored the hysteresis effect of soil under cyclic loading [25,26]. Bourgeois et al and Giannakos et al realized threedimensional numerical simulation of single horizontally loaded pile by means of the motion-hardening soil model based on D-P criterion and the Mohr-Coulomb criterion and studied the dynamic response of single pile under longterm loading, respectively [27,28]. Based on the nonlinear Winkler foundation model, Memarpour et al proposed a new stable and practical BNWF model by adopting the CPSI element considering decoupling, which can be used to calculate the lateral displacement characteristics of pile under the action of cyclic loading [29].…”

To explore the pile-soil interaction response in saturated sand under long-term horizontal cyclic loading, a series of indoor 1 g model tests were carried out with self-made loading equipment. In this paper, the self-made loading system and test program are introduced firstly. Then, the long-term horizontal cyclic loading-induced pile top cumulative displacement, the rotation angle, the mono-pile horizontal cyclic stiffness, the cyclic p-y curve, the pore water pressure, the soil settlement, and cracks around mono-pile are fully studied. Based on the experimental results, the pile-soil interaction response shows a two-stage characteristic with the change in cycle (N), and the short-term effects of horizontal cyclic loading are greater than the long-term effects. In the first 1000 cycles, the cumulative displacement of pile top, the rotation angle of mono-pile, and the pore water pressure could reach more than 90% of the final value. In addition, the cyclic p-y curve obtained by the test is generally smaller than the p-y curve calculated from the API specification, and the soil near the mono-pile will settle with annular cracks under the cyclic loading.

“…Bransby [11] applied load transfer-curve approaches; Chen and Martin [12] analysed arching effects in groups of piles with numerical simulation of horizontal planes; Hazzar et al [13] explored the validity of Broms' method using FLAC 2D; and more recently, Hazzar et al [14] compared 2D and 3D simulations for cohesive soils with FLAC and proposed a corrective approach for the 2D models. Although such simplified models reduce significantly the computational cost, making them a competitive tool in the long-term analysis, they are still far from being of general application, and thus researchers extensively employ 3D models [2,7,[15][16][17] in order to avoid errors and get more accurate results in the stress level of the soil mass and pile-soil interface.…”

The majority of wind turbine foundations consist of hollow monopiles inserted in the soil, requiring high computational effort to be numerically simulated. Alternative simplified models are very often employed instead. Three-dimensional solid models, in which the hollow structure and pile are substituted by solid cylinders with equivalent properties, are the most extended simplifications. Very few 2D models can be found in the literature due to the challenge of finding suitable equivalent properties and loads to fully represent the 3D nature of the problem. So far, very limited attention has been devoted to the accuracy of both 3D and 2D simplified models under dynamic and even static actions. Thus, in this paper, simplified 3D and 2D solid models are proposed and justified. An elasto-plastic constitutive model with accumulative degradation is used to simulate the soil behaviour, and frictional contact elements are implemented between the soil and pile to model their interaction. These simplified approaches are compared with the full 3D hollow model, under static and cyclic loads. The results demonstrate that the proposed simplified approaches are a reasonable alternative to the 3D hollow model, which allows researchers and designers to drastically reduce the computational effort in the simulations under long term conditions.
