“…According to Plumey et al (2011) and Ahmadi and Hajialilue-Bonab (2012), the failure mechanism in the soil for a flexural retaining structure fixed to the base and linear footing is composed of a rigid body and plasticised (or shear) area delimited by logarithmic spirals. The critical slip surface of an MSE wall divides the reinforced zone into an active and resistant zone.…”

The effect of preloading on mechanically stabilised earth (MSE) has remained an aspect difficult to quantify in design, particularly when considering different reinforcement types, stiffness values, and facing rigidity. This study analyses several scaled model tests on MSE walls under a strip footing load with a single unloading-reloading cycle. Scaled models were constructed as part of this investigation to expand the evaluation of previously constructed full-scale tests. The strip footing load and wall deflections were measured and compared with analytical models. The failure mechanism of the soil, before and after the strip footing load, was included in the study via the particle image velocimetry (PIV) method. The results indicate that the bearing capacity of a strip footing is higher for a rigid facing than for a flexible facing. PIV analysis results for the first and second loading step formed two failure lines with the angle (π/4 + φ/2). The deflection values in the second loading step, however, were smaller than those reached during the first loading in small-scale tests. Good agreement was observed between the proposed analytical method and experimental results for the second loading step, after taking into account the preloading effect.

“…Applications to mention are the anchoring of retaining walls, protection against rock‐fall or tower toppling, or stabilisation of caverns and tunnels . However, the design and stability analysis of such structures relies on (i) the national regulations, which may vary among countries, as it is acknowledged in BS EN 1537:2000 standard; (ii) experimental results; or (iii) assumed failure mechanism of simplified geometries . Usually, uniform load transfer from grout to ground and cylindrical or conical failure surface around the anchor are assumed.…”

This study extends the limit analysis techniques used for the computation of strict bounds of the load factors in solids to stability problems with interfaces, anchors and joints. The cases considered include the pull-out capacity of multibelled anchors and the stability of retaining walls for multiple conditions at the anchor/soil and wall/soil interfaces. Three types of wall supports are examined: free standing wall, simply supported wall and anchored wall. The results obtained are compared against available experimental and numerical data. The conclusion drawn confirms the validity of numerical limit analysis for the computation of accurate bounds on limit loads and capturing failure modes of structures with multiple inclusions of complex interface and support conditions.

“…This compressive strain may be owing to the plastic deformation of the soil and the resistance to the horizontal earth pressure of the rigid wall. Plumey proposed a spiral failure mechanism [31], in which the upper part of the wall is in a rigid state, and a plastic region occurs in a spiral form from the load point to the middle part of the wall, as shown in Figure 17. It was considered that compressive strain occurred in the reinforcement installed in the middle part (2.2 m, 3.4 m height) by applying force to the reinforcement while the soil moved along the plastic area.…”

Evaluation of Deformation Characteristic of Railway Subgrade Using Reinforced Rigid Walls with Short Reinforcement under Repetitive and Static Loads

A full-scale reinforced subgrade for railways (RSR) was constructed, and repetitive and static load tests were performed to analyze the deformation characteristics of reinforced rigid walls with short reinforcements for railway subgrades that require strict displacement restrictions. Load test results were obtained for four sections, in which the reinforcement arrangement (vertical spacing and length) and wall-reinforcement connection method were applied differently, and the behavior of the reinforced rigid wall was observed according to each parameter. A repetitive load of 500 kPa and a static load of 1000 kPa were applied to the outside of the reinforcement area to evaluate the behavior of the subgrade when utilizing short reinforcement. The test results confirmed the reduction of the settlement and horizontal displacement of the wall, owing to the restraining effect of the short reinforcement and rigid wall. In addition, it was observed that the greater the applied load, the greater the influence of the reinforcement on the behavior of the subgrade; this pattern was more marked in loads above the yield of soil.
