Three-dimensional finite element analysis has been carried out in order to study the response of retaining walls subjected to lateral earth pressure using ABAQUS/CAE. This study consists of analysis and design of cantilever, gravity type, and precast concrete retaining wall. It also shows comparative study such as distribution of stresses along with the deflection throughout the height of the retaining walls. The mathematical analysis procedure is adopted that entails selecting dimensions to meet the requirements of several codes and then evaluating the stability of the entire whenever the backfill load works on the wall. The stability of retaining walls in terms of sliding and overturning is evaluated. The three specified walls are then investigated using the ABAQUS software, and their behaviour is studied. In this analysis process, two components of the formed concrete wall; one is a base plate and another component is a cantilever sandwich panel, were projected. A headed anchor joins the prefabricated cantilever wall to the base plate, keeping the slab and wall together while also maintaining their integrity in the specific positions. The system requires a unique construction method for final assembly. Mainly two steps were followed for analysis: first, the different components for shear and bending moments, namely, heel and footplates, were designed, and then, the stability of the whole structure under load was evaluated. The ABAQUS program was used to simulate and analyse the stability of various walls, including traditional and precast concrete retaining walls. It was found on the basis of the observation that the prefabricated retaining wall is the most viable option out of the three as the stress and deflection in the former type are lowered.

“…In recent decades, geosynthetic-reinforced soil (GRS) structures have been constructed more frequently, such as subgrade [1,2], embankment [3,4], retaining walls [5][6][7], slopes [8,9], and landfills [10,11], because they have the advantages of low cost [12], simple construction, and environmental protection [8,13] and can deform without damage. High-density polyethylene (HDPE) geogrids, as an example of the important geosynthetics reinforcement materials, are commonly adopted in many GRS structures, such as reinforced soil retaining wall and reinforced slopes, especially for steep slopes [14][15][16], because of their excellent mechanical characteristics such as high strength, high elongation, and durability.…”

This paper describes a series of laboratory pullout tests that were performed to investigate the pullout behavior of high-density polyethylene (HDPE) uniaxial geogrid subjected to static and dynamic loading. Pullout tests were conducted on HDPE geogrid reinforced coarse sand under normal static loading (60–300 kPa), dynamic loading with different amplitudes (20, 40, and 60 kPa), and different frequencies (2, 4, and 6 Hz) by using the newly developed pullout apparatus. The results indicated that the pullout resistance of geogrid presented different growth patterns with the increase of normal loads under static loading. The amplitude and frequency both had significant effects on the interaction between reinforcement and soil, and the increment of the pullout resistance was 0.6 kN and 0.3 kN, respectively. The effect of dynamic loading on the soil-geogrid interface can be gradually equivalent to that of static loading corresponding to the balance position of dynamic loading with the increase of frequency compared with the static loading. The results of this study are helpful for the selection of the strength of the reinforcement in different locations and to simplify the study on the stress of reinforcement in reinforced soil structures under traffic loads.

“…However, the scale of the experiments is large, and it is important to deal with the similar relationship and boundary conditions of the model. Han et al [27] studied the notion that piles have been installed inside GRR walls to support bridge abutments and sound barrier walls. A pile in a GRR wall at a larger distance away from the back of the wall facing could carry more lateral load than that at a closer distance.…”
