TL;DR: In this paper, a new criterion is proposed for identifying the wall deformation level at which the active state of stress develops, which states that active stress develops when the angle of friction between the wall and the backfill soil reaches its maximum value.
Abstract: This paper outlines the results of unique shaking table experiments to determine neutral and active static and dynamic stresses and the points of application of corresponding total thrust generated by granular soils against rigid retaining walls and compares the experimental data with the well-known Coulomb and Mononobe-Okabe equations. A new criterion is proposed for identification of the wall deformation level at which the active state of stress develops. This criterion states that active stress develops when the angle of friction between the wall and the backfill soil reaches its maximum value. Based on the above criterion, experimental results show that the backfill soil enters the active state at much lower wall displacement levels than generally believed. An equation is proposed for calculating the displacement necessary to initiate active static or dynamic stress. This equation reveals that the displacement necessary to initiate active state increases with the height of the wall and decreases with backfill soil strength.

TL;DR: In this paper, the authors present experimental data of earth pressure acting against a vertical rigid wall, which moved into a mass of dry sand with a stress-free horizontal surface under various wall-movement modes.
Abstract: This paper presents experimental data of earth pressure acting against a vertical rigid wall, which moved into a mass of dry sand with a stress‐free horizontal surface under various wall‐movement modes. To investigate the variation of earth pressure induced by the rotation about a point above the top (RTT) and rotation about a point below the wall base (RBT) types of wall movement, the instrumented retaining‐wall facility was developed at National Chiao Tung University. Based on experimental data it is found that, for a wall under translational movement, the passive pressure distribution is linear and in good agreement with Terzaghi's prediction based on the general wedge theory. For a wall under either RTT or RBT mode, the magnitude of passive thrust and its point of application are significantly affected by the mode of wall displacement. However, if the parameter n indicating location of the center of rotation is greater than 2.0, the influence of movementmode on passive earth pressure becomes less impo...
