“…For compact granular soils, the peak friction angles calculated using plain strain tests are greater in magnitude than the values obtained using triaxial tests. By applying the correlation between triaxial tests and the maximal plane strain friction angle of 44 [33], it is possible to determine that 38 represents the latter. This value is typical for AASHTO (American Association of State Highway and Transportation Officials)-specified granular fill materials of superior quality intended for earth-retaining walls [3].…”

“…Furthermore, in examining the stability of such ER walls, inherent anisotropy in the soil medium has yet to be taken into consideration [31,32]. Finite element limit analysis evaluates the lateral earth pressure imposed on a retaining wall backfilled with geosynthetic-reinforced soil mass [33,34]. The influence of intrinsic anisotropy of the backfill soil on the stability of geosynthetic-reinforced ER walls is accounted for by adopting the method established by [35,36].…”

The present work aims to assess earthquake-induced earth-retaining (ER) wall displacement. This study is on the dynamics analysis of various earth-retaining wall designs in hollow precast concrete panels, reinforcement concrete facing panels, and gravity-type earth-retaining walls. The finite element (FE) simulations utilized a 3D plane strain condition to model full-scale ER walls and numerous nonlinear dynamics analyses. The seismic performance of different models, which includes reinforcement concrete panels and gravity-type and hollow precast concrete ER walls, was simulated and examined using the FE approach. It also displays comparative studies such as stress distribution, deflection of the wall, acceleration across the wall height, lateral wall displacement, lateral wall pressure, and backfill plastic strain. Three components of the created ER walls were found throughout this research procedure. One is a granular reinforcement backfill, while the other is a wall-facing panel and base foundation. The dynamic response effects of varied earth-retaining walls have also been studied. It was discovered that the facing panel of the model significantly impacts the earthquake-induced displacement of ER walls. The proposed analytical model's validity has been evaluated and compared with the reinforcement concrete facing panels, gravity-type ER wall, scientifically available data, and American Association of State Highway and Transportation Officials (AASHTO) guidelines results based on FE simulation. The results of the observations indicate that the hollow prefabricated concrete ER wall is the most feasible option due to its lower displacement and high-stress distribution compared to the two types. The methodology and results of this study establish standards for future analogous investigations and professionals, particularly in light of the increasing computational capabilities of desktop computers.

The active earth pressure acting on the rigid vertical retaining walls under translation mode has been investigated in this paper with a two-dimensional analytical method without prior hypotheses of the shape of soil arch, i.e. the trajectory of minor principle stress, which is totally different from with the existing method of combination of soil arch shape and horizontal flat-element analysis. Different emerging failure surface was compared and a parabolic surface was especially discussed in details. The proposed formula can be employed to predict the distribution of earth pressure and stresses in the failure zone. Furthermore, the analytical expression of the minor principle stress trajectory in the failure zone was derived from the stress equations. The results of the proposed analysis were compared with test data as well as the results of existing theories to validate its accuracy and applicability. The proposed distribution of earth pressure is in good agreement with the test data. Finally, a simple yet practical formulation was established to conveniently estimate active earth pressure in field.
