“…The commonly used RWs include the gravity RWs [1,2], which rely on the balance between the self-weight of the RW and the earth pressure to maintain the stability of the wall and have disadvantages including long construction periods and poor greening function; gabion RWs [3,4], which are flexible gravity retaining structures formed by stacking gabion cages containing various grades of stone in an orderly manner; reinforced earth RWs [5,6], which are formed by adding steel bars in the soil to stabilize the soil by the friction between the steel bars and the soil, but their construction quality is greatly affected by the construction site factors and slope surfaces are required to be gentle; cantilever/counterfort RWs [7,8], which maintain stability by the weight of the fill on the bottom plate but have the disadvantages of complex construction technology, long construction periods, and excessive corrosion of drain pipes; and sheet pile walls [9][10][11], which uses baffles to block the soil between the deeply buried piles and they have similar disadvantages to those of the cantilever/counterfort RWs.…”

“…The investigations on the load-bearing characteristics of sheet pile walls include the study of Mattos et al [9], who evaluated several limit equilibrium design methods available in international standards and manuals using the suggested probabilistic design procedure based on multiphase Monte Carlo simulations. The results revealed that the safety coefficient and soil/wall friction significantly affect the relative conservativeness of these design methods.…”

Prefabricated walls are frequently utilized as retaining structures in different applications. A new type of prefabricated greening ecological retaining wall (PGERW) is proposed in this research. Full-scale tests and numerical simulations were conducted to investigate the stress characteristics of the PGERW. To this end, the load–stress relationship, load–displacement relationship, and crack development of the retaining wall columns were carefully evaluated. It was found that when the load acting on the 3 m high column reached the ultimate load-bearing capacity (about 150 kN), an “arc + 7”-shaped crack pattern emerged. A V-shaped crack composed of bolt–chamfer cracks formed when the load applied to a 2.5 m high column reached the ultimate load-bearing capacity (about 335 kN). The design of hollow thin-walled columns can effectively reduce the amount of concrete used and, as a consequence, reduce its carbon emissions, while meeting the design strength requirements of the retaining wall. The PGERW addresses the challenges of improving the extent of greening and drainage performance of traditional prefabricated retaining walls. It has excellent applicability to highway slope construction and therefore can be applied in several contexts.

In urban environments, temporary excavation support systems (ESSs) are intensively recommended during the construction process of structures with underground levels to preserve nearby structures and maintain the excavation sides. Once the foundations and basements are constructed, these systems are rendered useless. As a result, integrating the temporary ESS into the building foundation may have significant benefits. Therefore, the main aim of this paper was to investigate the behavior of Secant Pile Walls (SPWs) through fifteen model tests with an acceptable scale on an axially loaded SPW embedded in medium and dense sand. This study considered several factors to define wall behavior, such as normalized lateral deflection (δh/Ht%), the vertical deflection of the SPW (δvw/Ht%), vertical ground settlement (δv/Ht%), and settlement influence zone (Do). These factors were investigated and analyzed under the influence of a set of parameters including normalized penetration depth (He/Hc), sand relative density (Dr), and surcharge load density (Wsur). The findings demonstrated that SPWs had structural and overall stability features to withstand lateral earth pressures as well as applied axial loads. Generally, increasing the He/Hc ratio further than a limit value of 2.0 for the same surcharge load had a limited impact on the ultimate axial capacity, particularly in the case of dense sand. The location of the pivot point (ε′) extended from 0.24 to 0.41He from the wall tip, with a mean value of 0.34He and 0.29He for the values of Dr = 80 ± 2%, and 60 ± 2%, respectively. Other issues were also discussed for selected samples, including an analysis of the wall's bending moments and any potential wall buckling. Finally, to correlate the experimental data with the theoretical values, a modification factor for the pile static formula was developed by using nonlinear regression analysis with a significant prediction accuracy with an R2 of 0.94.
