Seeking Out Failure: The Random Finite Element Method (RFEM) in Probabilistic Geotechnical Analysis
The paper describes probabilistic analyses in geotechnical engineering which use the Random Finite Element Method (RFEM). The method rigorously includes the influence of spatially variable soil properties on design outcomes relating to familiar geotechnical analyses such as bearing capacity, slope stability and limiting earth pressure. Two important observations from these studies are highlighted: Firstly, by making no a priori assumptions about the shape or location of the critical failure mechanism, the RFEM allows the mechanism to "seek out" the critical path through the soil. Secondly, the analyses indicate that there is a critical spatial correlation length that leads to a minimum strength of the soil mass.
