“…Historically, Coulomb pioneered the investigation of lateral earth pressure on the retaining wall by assuming a plane failure surface under limit equilibrium conditions (Coulomb 1776). Various developments rooted in Coulomb earth pressure theory have been reported considering more general ground and loading conditions, for examples in recent years, surcharge loading (Motta 1994;Greco 2005), seismic effects (Wang et al 2008a;Ahmad 2013;Brandenberg et al 2015), cohesive-frictional backfill (Ahmadabadi and Ghanbari 2009;Chen 2014;Xu 2015), and different slip surfaces (Li and Liu 2010;Ouyang et al 2013;Patki et al 2015).…”

This paper presents a general solution for active earth pressure acting on a vertical retaining wall with a drainage system along the soil-structure interface. The backfill has a horizontal surface and is composed of cohesionless and fully saturated sand with anisotropic permeability along the vertical and horizontal directions. The extremely unfavourable seepage flow on the back of the retaining wall due to heavy rainfall or other causes will dramatically increase the active earth pressure acting on the retaining walls, increasing the probability of instability. In this paper, an analytical solution to the Laplace differential governing equation is presented for seepage problems considering anisotropic permeability based on Fourier series expansion method. A good correlation is observed between this and the seepage forces along a planar surface generated via finite element analysis. The active earth pressure is calculated using Coulomb's earth pressure theory based on the calculated pore water pressures. The obtained solutions can be degenerated into Coulomb's formula when no seepage exists in the backfill. A parametric study on the influence of the degree of anisotropy in seepage flow on the distribution of active earth pressure behind the wall is conducted by varying ratios of permeability coefficients in the vertical and horizontal directions, showing that anisotropic seepage flow has a prominent impact on active earth pressure distribution. Other factors such as effective internal friction angle of soils and soil/wall friction conditions are also considered.

“…Some researchers calculated the active earth pressure on retaining wall under movement modes. Chen and Li further analyzed the active earth pressure on retaining wall considering soil tensile strength and the effect of wall displacement on soil cohesive and friction angle under T mode, respectively 12,13 . Wang adopted the horizontal flat‐element method to determine active earth pressure on rigid retaining wall under RT mode 14 .…”

Both wall movement mode and soil arching are important to the active earth pressure on rigid retaining wall, but the method of active earth pressure under wall movement modes considering arching effects is yet to be studied. A series of minor principal stress trajectories described by the power function with the exponent b is assumed to analyze the soil arching effect using the equivalent friction coefficient between adjacent soil layers. The horizontal Winkler elastic foundation beam model induced by wall movement modes is presented. Then based on the trajectories and wall movement modes the horizontal flat-element method of active earth pressure on rigid retaining wall is improved and verified.The active earth pressures on the retaining wall under translation (T), rotation about top (RT) mode and rotation about bottom (RB) mode calculated by the improved method are in a better agreement with the experimental results than other analytical studies. The application point of the resultant active earth pressure on retaining wall increases from 0.25 H to 0.49 H with varies of wall movement modes considering soil arching effect. The larger equivalent friction coefficient is, the more notable soil arching effect is. The most notable soil arching effect is described by the approximate linear minor principal stress trajectory whose power function with exponent of b approaches zero from positive direction. The active earth pressure on retaining wall under RT mode considering the most notable soil arching effect is simplified and suggested for the engineering practice.

“…General rules, retaining walls are distinguished by the material used, the load transfer method, workload, and production technology [19]. In constructing a retaining wall, the most important thing is to know the active ground pressure [2,7,9,10,13], the seismic pressure [3], the passive soil pressure [6,[20][21][22], the active soil pressure [23,26], static and dynamic soil pressure [4], and lateral pressure [5].…”
