Calculation of structural forces for propped retaining walls, XIII ICSMFE, 1994, New Delhi, India, pp. 823 - 826.

This paper presents a summary of the results of a numerical parametric study on the effects of wall stiffness and K„ on the behaviour of single propped embedded retaining walls. By modifying Rowe's wall flexibility number, p. to include both the wall and soil stiffness it is shown that results from analysis based on different soil stiffness profiles and of different wall geometries can be normalised. Finite element predictions of maximum wall bending moment and prop force are compared with values from simple limit equilibrium calculations. Coefficients relating the finite element and limit equilibrium results are established and the manner in which they vary with both wall stiffness and K.„ value are presented. A design procedure combining these coefficients with standard limit equilibrium analysis is proposed. This results in the enhancement or reduction of bending moments and prop forces calculated by limit equilibrium depending on wall stiffness and in situ stress conditions.
