Three-dimensional finite element analysis for uplifting independent helix plate anchor in uniform clay

Physical and Finite Element Models for Determining the Capacity and Failure Mechanism of Helical Piles Placed in Weak Soil

“…However, helical piles are superior to conventional pile foundations [6][7][8] because they provide more resistance due to the helix [9,10]. 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 helica piles are relatively limited compared to conventional pile foundations, and previou studies mostly focus on the uplift behavior [11][12][13][14][15][16][17][18][19]. In addition, it can be expressed tha numerical efforts regarding the failure mechanism of helical piles are quite limited [11,20 28].…”

“…To briefly mention the scope of the study, it aims to assess the behavior of helica piles with the physical model tests and also to present the results obtained from 2D and 3D finite element models. 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].…”
