TL;DR: In this article, a series of model tests with the horizontally translating rigid walls are designed to determine the distribution of active earth pressure on retaining walls, and the results show that there are three stages of soil deformation under retaining wall translation: the initial stage, the expansion stage and the stability stage.
Abstract: To determine the distribution of active earth pressure on retaining walls, a series of model tests with the horizontally translating rigid walls are designed. Particle image velocimetry is used to study the movement and shear strain during the active failure of soil with height H and friction angle ϕ. The test results show that there are 3 stages of soil deformation under retaining wall translation: the initial stage, the expansion stage and the stability stage. The stable sliding surface in the model tests can be considered to be composed of two parts. Within the height range of 0.82H–1.0H, it is a plane at an angle of π/4+ϕ/2 to the horizontal plane. In the height range of 0–0.82H, it is a curve between a logarithmic spiral and a plane at an angle of π/4+ϕ/2 to the horizontal. A new method applicable to any sliding surface is proposed for active earth pressure with the consideration of arching effect. The active earth pressure is computed with the actual shape of the slip surface and compared with model test data and with predictions obtained by existing methods. The comparison shows that predictions from the newly proposed method are more consistent with the measured data than the predictions from the other methods.

TL;DR: In this article, the relations between boundary yielding and the state of lateral stress in unreinforced and reinforced sand backfills have been investigated at laboratory model scale, and it has been shown that lateral expansion of the backfill is necessary to attain the minimum force acting on a retaining structure.
Abstract: The relations between boundary yielding and the state of lateral stress in unreinforced and reinforced sand backfills has been investigated at laboratory model scale. The results have shown that lateral expansion of the backfill is necessary to attain the minimum force acting on a retaining structure. The study has also shown that such expansion of a reinforced backfill can reduce the lateral stresses to significantly below that corresponding to the "active" earth pressure condition for an unreinforced fill. Descriptions are also given of methods of achieving controlled yielding of lateral boundaries to attain the minimum stresses acting on a wall and thus avoid problems of unserviceability of the wall or facing units. Although the results were obtained from laboratory models, such information is of considerable significance in relation to the economic design and construction of full-scale retaining structures.

TL;DR: In this paper, the authors investigated the effect of repeated loads on earth retaining structures that support backfills carrying moving loads, such as bride abutments, basement walls, and basement walls.
Abstract: The pressures on earth retaining structures that support backfills carrying moving loads have always been estimated by using methods that assume these loads to be applied in a static condition: the effect of these loads being repeated is not considered. The failure of some structures like bride abutments and basement walls, which support loads from moving vehicles, made it necessary to carry out these investigations.
