“…The response of the structure was noted at different locations, and the stress concentration is found comparatively more in the immediate soil, which is present just below the foundation. Xie et al (2017) [40] have calculated the bearing capacity of the high-piled wharf structures using the same software ANSYS. In the analysis, the piles were considered as the target element and soil as a contact element.…”

Laterally loaded piles are generally used where high lateral load acts on the structures. Vertical piles along with batter piles are used in structures such as chimneys, towers, dock and harbor structures, and high-rise buildings. Various techniques have been used in literature to solve the laterally loaded pile problems. Among them p-y method is preferred over all other methods. Various researchers have provided analytical solutions for vertical and batter pile problems and are discussed in this paper. Experimental investigations were also carried out by various researchers on vertical and batter piles, indicating that the negative batter piles offer large resistance to lateral loads when compared with the vertical piles. The deflection values obtained from the analytical solutions were also compared with the model tests and were found to be in a good agreement. Numerical modeling conducted by various researchers on vertical and batter pile foundation by various researchers is also discussed in this paper.

“…Any existing structural finite element analysis software can be applied to establish the 3D FEM of a frame-type wharf structure [18]. For this paper's study, Structure Analysis Program 2000 (SAP2000) [19] is selected to calculate the internal force results of every significant component of a frame-type wharf's FEM.…”

The wharf, which was built in the Three Gorges Reservoir of China, is constructed as a layered frame-type structure for adapting to large water level fluctuations that exceed 30 m. These large fluctuations cause the frame-type structure to exhibit a considerably higher number of load case combinations than traditional marine highpiled wharfs. To estimate the most adverse combined internal force and the corresponding unfavourable load case combinations of significant components for multilayered frame-type wharf structures in the Three Gorges Reservoir of China, a high-efficiency algorithm is developed in this study. This algorithm can skilfully transform the computational mode of load case combinations into a matrix operations process by computer programming. By applying the proposed algorithm, the number of load case combinations for eight significant components of frame-type wharf, including piles, columns, beams, braces and berthing components, are resolved to a total of 21 from the original quantity of more than six billion. This high-efficiency algorithm can provide powerful technical support for evaluating the bearing capability of multilayered frame-type wharfs in the Three Gorges Reservoir of China.

“…The direction of pile inclination is called the front of the pile, and the opposite is called the back of the pile. Poulos [22] classified piles as rigid and flexible according to the coefficient Kr, as shown in Equation (1), where EpIp is the bending stiffness of the pile section, Lp is the embedment depth, and Es is the tangent modulus of soil. In this paper, EpIp = 1.98 kNm 2 and Kr = 2 × 10 −4 .…”

“…Batter piles are widely used in infrastructure construction. Its high impedance to the lateral load makes it irreplaceable in the design of bridges, wharves, and transmission towers [1]. They also have disadvantages, as it is generally accepted in academia that under vertical loads, batter piles will produce a sizeable additional bending moment and be accompanied by the horizontal and vertical displacements [2,3].…”

Under the action of vertical loading, batter piles rarely appear individually, as they undergo horizontal and vertical displacements at the same time and produce a sizeable additional bending moment. However, previous studies have mainly focused on a single batter pile, which is inconsistent with engineering practices. Although single pile tests can easily reveal its working behavior, they also ignore two important factors, namely, the internal force redistribution caused by the deformation limitation of the mirror-like pile, and the interaction between the symmetrical piles and “clamped” soil (the soil between two symmetrical piles). Therefore, this paper took symmetrical batter piles as the test object to explore the influence of the two factors on the load transfer mechanism. Moreover, the deformation mode, distribution of inertial forces, and group effect of symmetrical batter piles were also discussed. The results showed that the “clamping effect” caused by the pile deformation had a significant impact on the load transfer. Under vertical loading, the flexible symmetrical floating batter piles were the only deformation mode. Under the constraint of the cap and mirror-like batter piles, the symmetrical conformation partially compensated for the disadvantage of the additional bending moment.
