Probabilistic Analysis of a MSE Wall Considering Spatial Variability of Soil Properties
The results of probabilistic analyses of a mechanically stabilized earth (MSE) wall with geosynthetic reinforcement are presented. The analyses consider spatial variability of reinforced and foundation soil properties using the 2D non-circular random limit equilibrium method (RLEM). In this study, it is assumed that the reinforced soil is a purely frictional soil, while the foundation is a cohesive-frictional (c-ϕ) soil. A negative cross-correlation between cohesion and friction angle and a positive cross-correlation between cohesion and unit weight, and between friction angle and unit weight are also assumed. It is shown in this study that, considering only random variability of soil properties results in an overly-conservative probability of failure for design. However, considering spatial variability of soil properties plus cross-correlation between soil input parameters provides an estimate of probability of failure which is in better agreement with the margin of safety implied using a deterministic factor of safety.
