Probabilistic Analysis of Foundation Settlement on Multilayered Soil with a Complex Layer-Boundary

摘要

This paper describes the probabilistic analysis of settlement of shallow foundations on a multilayered soilrnprofile with a complex layer-boundary. Each layer is modelled as a separate random field of soil elasticrnmodulus properties in order to represent spatial variability. The soil layer boundaries incorporate complexrnfeatures such as inclination, undulation and a transitory region, which attempts to model realisticrngeological features. The analysis investigates the failure probability due to excessive differentialrnsettlement of two shallow footings founded at the surface of a two layer soil profile.
