“…In general, software programs based on finite element methods more than finite difference methods or codes of particle methods such as the material point method are used in helical foundation modeling [181]. For familiarization with the helical foundation modeling using Abaqus, Plaxis, FLAC, and MIDAS software programs, respectively the studies conducted by Merifield [21], Rawat and Gupta [190], Pérez et al [218], and Polishchuk and Maksimov [207] have provided the proper information for readers. The other question about modeling is usually a type of modeling (twodimensional or three-dimensional?).…”

The use of piles, helical anchors, in general, helical foundations has considerably increased in the last 30 years. The adoption of this technology in the international and domestic codes of each country, as well as in research and studies, and, finally, the publication of numerous books and papers in this area, and the existence of manufacturers' products, committees, and contractors of this technology has contributed to its expansion and development. However, such methods have progressed at a very slow pace in many countries, especially in developing countries. This paper attempts to assess the global advancement of the helical foundations by reviewing 292 papers from 1990 to 2020 and comparing the related research findings. This will help clarify the issue and determine the scope of technological progress. On the other hand, collecting valuable papers in this area will make it easier for researchers to make further research.Subsequently, the characteristics of this technology are highlighted and the reasons for its lack of progress in developing countries are addressed. For this purpose, a questionnaire is sent to researchers, developers, designers, and contractors of the geotechnical projects. The purpose of this questionnaire is to specify the type of existing projects, the soil type of project site, the degree of familiarity with the helical foundation technology, the reasons for not using this method, and the solutions available to expand and develop this method. Finally, there are suggestions to develop this approach and the issues that need further research.

“…After these tests, some parametric studies were performed to define an optimum equivalent shaft length. Numerical investigations have also been conducted about the axial compression behaviour of helical piles, as can for instance be seen in [4,[8][9][10]. Full-scale loading tests and numerical analyses were performed by Livneh and Naggar [4] in order to investigate axial compression performance of helical piles.…”

“…They concluded that mechanism of load transfer from cylindrical shear failure to individual bearing failure changes when the spacing ratio (s/ D h ) is changed from 1.5 to 2. Polishchuk and Maksimov [10] investigated full-scale helical pile field tests results in clay soils using the finite element analysis. They reported that model results are in accordance with test results.…”

An investigation into axial compression capacity of single helical piles placed in dry sand through laboratory model tests and numerical analyses is presented. The compressive bearing capacities were compared with existing theoretical results given in the literature. Laboratory model tests were performed to determine some design parameters of helical piles such as the plate number, plate diameter, and plate spacing. A good correspondence between experimental, numerical, and theoretical results was established.

“…The behavior of single and multiple helical piles placed in loos sandy soil (RD = 30-35%) will be examined under the compression load; and in thi regard, the effects of parameters such as helix number, helix distance, and upper heli diameter will be investigated in terms of bearing capacity and failure mechanism Despite the abundance of usage areas of helical piles, the increase in application, and the advantages they provide, it can be seen that research and design methods for helical piles are relatively limited compared to conventional pile foundations, and previous studies mostly focus on the uplift behavior [11][12][13][14][15][16][17][18][19]. In addition, it can be expressed that numerical efforts regarding the failure mechanism of helical piles are quite limited [11,[20][21][22][23][24][25][26][27][28]. Therefore, since there is a necessity in the literature, albeit at a limited level, the compression behavior of helical piles has been investigated using physical model tests and two-dimensional (2D) and three-dimensional (3D) finite element models.…”

The foundations of particular engineering structures, including marine and jetty structures, mooring systems for submerged platforms or those on the ocean surface, and transmission towers, are subjected to various external loads including compression, uplift, and lateral loads. In such cases, to improve the soil resistance below foundations, pile foundations such as helical piles, anchored piles, and batter piles are commonly preferred, depending on the in situ conditions. Helical piles, increasingly used as an alternative foundation to conventional piles, are placed in the soil body by rotating with torque. This paper deals with the contribution of a helical pile in improving loose sandy soil, and the main purpose is to study the effect of the helix-buried depth on the load-bearing capacity and failure mechanism. The investigated variables include the distance between helixes, the number of helixes, and the diameter of the upper helix. Physical model tests were conducted, and two- and three-dimensional numerical analyses were performed by using the finite element method with an advanced soil model to illustrate the failure mechanisms of helical piles. The aim was to reveal the efficiency of the finite element method in modelling helical piles placed in weak sandy soil. A simplified linear geometry for helixes was established in a two-dimensional finite element model whereas a real geometry for helixes, which was a more realistic approach, was created in a three-dimensional finite element model. The results show that the three-dimensional model indicates better agreement with the physical model compared to the two-dimensional model, and all investigated variables highly affect the load-bearing capacity of helical piles.
