- Methods available for the determination of the force system acting on rigid retaining walls under static or seismic conditions are reviewed. The function of random soil parameters is described statistically. Two techniques capable of providing approximations to the statistical values of functions of random soil properties are investigated. It is determined that the point estimates method is more accurate and easier to implement than the series approximation method. In a similar investigation of procedures available to describe the spatial variability of soil properties, it is concluded that the quasi-stationary autoregressive method provides a better approach than the average mean-crossings distance method or the moving average method. The effect of important material, loading, and model parameters on the force system against rigid retaining walls is considered.
