“…However, in the present study, lateral loading on pile per unit length is increased rapidly due to an abrupt collapse of the retaining structure. Contrary to previous studies, the soil movement is induced due to collapse of the retaining wall rather than due to excavation activity [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22]. The results of this study are not directly scalable to full-scale conditions because of the low pressure (high dilation/low stiffness) response in the present study.…”

“…Researchers have developed analytical, theoretical and experimental approaches to predict the response of pile foundations exposed to soil movement. However, most of the studies considered the cases of excavations supported by retaining structures [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25]. Abbas et al [26] performed numerical analysis using Plaxis and found that the group configuration has a significant effect on the performance of pile groups subjected to lateral loading.…”

Excavations supported by retaining structures are very common in the construction of new structures in urban and hilly areas. This paper presents behaviour of model piles of various configurations, when exposed to soil movement induced by collapse of the retaining structure. The performance of pile groups varies significantly with the distance between the pile group and the retaining structure. A pile row parallel to the retaining structure experiences large displacement as compared to pile rows that are perpendicular to the structure.

“…In the past, piles were unquestionably strengthened [4]. Nowadays, the designers are minimizing the length of reinforcing bars; therefore, they are scaling back the number of piles [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. This reduction needs excellent separation for the cases wherever the piles would entirely or partly require reinforcement, and in cases where the reinforcement has been eliminated.…”

This study was focused on the performance of the pile force at the lateral load of an arched bridge. The effect of the compression of arch bridges creates a large horizontal load. Therefore, it is one of the most important factors in the dimensioning of piles. The study aims to make a comparative study between the results obtained in the field, and those obtained by a 3D model defined as a Finite Element (FE) of a drilled pile, subjected to different lateral loads applied at exact time intervals. Moreover, the study was intended to determine the influence of the lateral load applied to a different pile diameter using the FE model. Thus, the unified FEA software Abaqus™ by Dassault systèmes®carried out various processing procedures, namely soil FE modeling, pile FE modeling, soil-pile interface, Mesh, and boundary conditions, to carry out an effective and predictive piles behavior analysis. Based on the Mohr-Coulomb criterion, the soil is considered to be stratified with elastoplastic behavior, whereas the Reinforcement Concrete Pile (RCP) was assumed to be linear isotropic elastic, integrating the concrete damage plasticity. Since the bridge is an arched bridge, the lateral load induced was applied to the head of the piles through a concentrated force to check the pile strength, for which the displacement, stress and strain were taken into account throughout, along the pile depth. The lateral displacement of the pile shows a deformation of the soil as a function of its depth, with different layers crossed with different lateral loads applied. Thus, from the study comparing the results of the FE measurements with the data measured in the field, added to the statistical analyses are as follows: Decrease of the displacement and stress according to the diameter, taking into account the different diameter. The foundations receive loads of the superstructure to be transmitted to the ground. Thus, the piles are generally used as a carrier transmitting loads on the ground. One of the important factors in the durability of the bridge depends more on the strength of these piles. This makes it necessary to study the reinforced concrete foundations because of their ability to resist loads of the structure, and the vertical and lateral loads applied to the structure. This implies an evaluation of the responses of the RCP according to the different lateral loads.

“…However, the group efficiency obtained based on the ultimate lateral loading can be higher than that at a given deflection. Kim and Yoon [ 20 ] carried out the static loading tests on the different pile arrangements. They calculated the group efficiency when the deflection was reached 0.1 d .…”

Grouped and single pile behavior differs owing to the impacts of the pile-to-pile interaction. Ultimate lateral resistance and lateral subgrade modulus within a pile group are known as the key parameters in the soil-pile interaction phenomenon. In this study, a series of experimental investigation was carried out on single and group pile subjected to monotonic lateral loadings. Experimental investigations were conducted on twelve model pile groups of configurations 1 × 2, 1 × 3, 2 × 2, 3 × 3, and 3 × 2 for embedded length-to-diameter ratio l/d = 32 into loose and dense sand, spacing from 3 to 6 pile diameter, in parallel and series arrangement. The tests were performed in dry sand from Johor Bahru, Malaysia. To reconstruct the sand samples, the new designed apparatus, Mobile Pluviator, was adopted. The ultimate lateral load is increased 53% in increasing of s/d from 3 to 6 owing to effects of sand relative density. An increasing of the number of piles in-group decreases the group efficiency owing to the increasing of overlapped stress zones and active wedges. A ratio of s/d more than 6d is large enough to eliminate the pile-to-pile interaction and the group effects. It may be more in the loose sand.
