Bearing Capacity Of Shallow Foundations Considering Geological Uncertainty And Soil Spatial Variability, Qi-Hao Jiang, Jin-Tong Wang, Bo Hou, Dong-Ming Zhang, Jin-Zhang Zhang

Rock and Soil Mechanics

The bearing capacity of shallow foundations is significantly affected by stratum uncertainty, mainly including geological uncertainty and spatial variability of soil properties. The influence of geological uncertainty and soil spatial variability on the bearing capacity of shallow foundations has been separately investigated in previous studies. This study aims to develop a general probabilistic computational framework to reveal the effects of geological uncertainty and spatial variability of soil properties on the bearing capacity of shallow foundations, in which the geological uncertainty is simulated by Markov random field and the soil spatial variability is characterized using log-normal random field in different strata …
