To deal with the case of a rigid retaining wall built close to a stable rock face with cohesionless backfill, analytical solution methods Proposed by Spangler- Handy and Sokolovskii are modified. The modified solution methods, taking into account different friction angles along the wall and the rock face, can estimate the developed static or dynamic horizontal earth pressures behind vertical retaining walls experiencing various types of outward wall movements. The range of application of each proposed method, which is represented by the ratio of the distance between the wall and the rock face to the height of the wall, is compared with each other and also is examined for different wall friction angles as well as soil friction angles. Further, the result predicted by the modified Spangler - Handy solution method is compared with that from the experimental model test on sand. The comparison shows in general good agreements at various stages of retaining wall rotation about its toe. Finally results of analytical parametric study, together with the design charts, are presented to demonstrate the effects of wall friction angles and horizontal acceleration coefficients.
