“…Experimental studies have also revealed similar benefits. [9][10][11] The experimental study performed by Escoffier [12] showed that the response of a twoby-one batter pile group was highly influenced by the frequency content of loading. It has also been suggested that the inadequate performance of inclined piles has been due to poor design rather than the fundamental behaviour of the pile itself.…”

A simplification of existing analytical solutions together with an extended hybrid model is proposed for estimating the horizontal impedance of batter pile groups subjected to harmonic loading. The solutions are given through compact interaction factors and analogue pile‐soil‐pile interaction elements. Benefits and pitfalls of the simplified models are elucidated through a comprehensive comparison with a refined finite element model. The effect of varying center‐to‐center pile distance with respect to depth is discussed. It is shown that the analytical model is able to represent pile‐soil‐pile interaction rather well within the specified framework.

“…Zhou Dequan et al [16] set an inclined pile at different angles in the model sand and applied a horizontal load to the top of the pile, so as to obtain the change law of p-y curve characteristics with the inclination angle and pile bottom constraint conditions. Chen Wenlong et al [17] carried out a vibration table comparison test of inclined and straight piles in saturated sand and discussed the seismic performance of inclined pile foundations from three aspects: superstructure acceleration, pile top shear force and the pile body bending moment. In recent years, many scholars have carried out studies on the seismic performance of inclined pile foundations through numerical simulation [17][18][19][20][21][22].…”

With the development of all types of new special-shaped arch bridges, the deformation of the pile foundation of special-shaped steel arch bridges has a great influence on the superstructure, and the requirements for it are strict. In addition, the force of the inclined pile group under an earthquake is complicated. In this paper, based on the Zhuhai Jindao Bridge project, the finite element numerical model is established in order to study the dynamic response and parameter influence law of an inclined straight pile group foundation under earthquake action. After a thorough analysis of the results of the simulation, it was found that under the action of an earthquake, the inclination angle of inclined piles has a significant influence on the seismic ability of pile group foundations. When the inclination angle of an inclined pile is 5°, the ability of the inclined pile group foundation to resist deformation can be effectively improved, and the load distribution of the pile top is more reasonable.
