“…For example, in the reduced-scale model test conducted by Mohammed [16], at the pile head displacement equal to 20% the pile diameter, the lateral capacities of the pile located at the 2D offset behind the wall facing decreased by 10% and 26% as compared with those located at the pile offsets of 4D and 6D, respectively. While in the reduced-scale model test conducted by Jawad et al [30], the reduction in the lateral capacity of the pile located at the 2D offset was 28% as compared with that at the 4D offset. In the full-scale tests of piles behind the facing of the concrete-panel MSE wall with steel reinforcement (i.e., steel rib and welded wire grid), the lateral capacity of piles increased with increasing the pile offset behind the wall facing.…”

“…suggested that the lateral pressure distribution from the pile foundation on the MSE wall face decreases linearly or nonlinearly with the wall depth. Jawad et al [30] measured the additional lateral earth pressure along the back face of the wall using earth pressure cells. The test results from Jawad et al [30] showed that the additional lateral earth pressure distribution with the wall elevation was non-linear.…”

“…However, some studies showed that an increase of the reinforcement length to wall height ratio more than one had an insignificant effect on the lateral load capacity of the pile and the wall facing displacement. Jawad et al [30] conducted a three-dimensional numerical analysis and investigated the effect of the reinforcement length to wall height ratio (e.g., 0.7, 1.0, and 1.3) on the lateral load capacity of the pile, the wall facing displacement, and the lateral earth pressure behind the wall facing. Their numerical results showed that the load-displacement curves, the wall facing displacements, and the lateral earth pressures behind the wall facing for the piles with the reinforcement length to wall height ratios of 1.0 and 1.3 were almost the same, indicating that the increase of the reinforcement length to wall height ratio more than 1.0 had an insignificant effect on the lateral load capacity of the piles placed at the 2D offset.…”

“…This phenomenon happened because there was only one reinforcement layer supporting the top panel. Jawad et al [30], after conducting reduced-scale model tests, found a relationship between the pile IOP Publishing doi:10.1088/1757-899X/1260/1/012004 9 head displacement and the maximum wall facing displacement by including the test results from Pierson [15]. The reason for selecting these field tests instead of other tests mentioned before is that these tests had similar test conditions to the model tests in terms of wall type, pile stiffness, reinforcement type, and pile toe depth (i.e., at the base of the MSE wall).…”

“…Jawad et al [30] measured the additional lateral earth pressure along the back face of the wall using earth pressure cells. The test results from Jawad et al [30] showed that the additional lateral earth pressure distribution with the wall elevation was non-linear. The maximum lateral earth pressure was located at an elevation of 80% the wall height, while the minimum lateral pressures were observed at the bottom and top of the wall.…”

Pile foundations have been increasingly installed within mechanically-stabilized earth walls (MSE) on rocks or compressible soils to support structural loads. Integral abutment bridges, sound walls, and traffic signs are common examples of the structures supported by pile foundations installed within or behind MSE walls. These structures are often subjected to lateral loads resulting from earthquakes, traffic loads, wind loads, and/or thermal expansion and contraction of bridge girders. Typical approaches available to design MSE walls are limited to MSE walls without pile foundations present within reinforced fill. To minimize the interaction between piles and the MSE wall, designers often suggest to place the piles at a distance of six to eight times the pile diameter and/or isolate the piles from the MSE wall by using corrugated pipes. These suggested designs lead to increasing the cost of projects by increasing the length of bridge spans or the diameter of piles and requiring pile embedment. Recently, several studies have been conducted to understand the interaction between piles and MSE walls when the piles are constructed within and close to wall facing. This paper provides a literature review on full-scale tests, reduced-scale tests, and numerical studies of piles constructed within or behind MSE walls. The review will focus on the effects of three key influence factors on lateral capacities of laterally-loaded piles and facing deflections of MSE walls including the plie location behind the wall facing, the ratio of the reinforcement length to the wall height, and the stiffness of the reinforcement layer. This paper will also discuss the available approaches to estimate the forces in the reinforcement layers and the lateral earth pressures behind the MSE wall facing due to the laterally-loaded piles.

Reinforced soil or mechanically stabilized earth (MSE) wall structures offer straightforward construction techniques as an alternative to conventional retaining earth walls. The benefits of MSE wall structures are their low cost, rapid construction, minimal ground occupation, and high tolerance for differential settlements. In the past, a vast amount of research has been conducted on this specific topic, but there is no state-of-the-art overview on the general reinforced soil walls subject. In this paper, a bibliometric review of MSE walls literature is carried out to provide multiple data points regarding the state-of-the-art in MSE wall publications. To present/demonstrate the main traditional applications, current utility, and last developments of MSE walls, a thematic/keyword cluster categorization is performed to catalog and organize the numerous applications analyzed and published in the last 4 decades. Furthermore, a discussion of MSE wall characteristics is conducted to assist researchers in expanding their understanding of potential future research areas.
