DOI: 10.1016/j.sandf.2017.11.006
Abstract: Abstract The spatial variability of soil properties is often assumed to be modeled as stationary or weakly stationary random fields in slope reliability analyses. However, abundant site-specific data have revealed that the mean and standard… read more here.
