Excavation-Induced Structural Responses Due to Inherent Spatial Variability of Soils
In this paper, the effect of soil spatial variability on the soil-structure interaction in braced excavations is investigated. The excavation-induced wall deflection, wall bending moment, wall shear force, and strut force are modeled by finite element method implemented with non-linear soil constitutive relationships. The vertical spatial variability of sands is simulated by random field theory. This random finite element modeling (RFEM) is realized with the use of Monte Carlo simulation. As a result, the statistical distributions of the excavation-induced responses are probabilistically assessed. It is illustrated that the soil spatial variability has significant influence on the mean value and standard deviation of maximum wall bending moment, maximum wall shear force, and strut axial force. Three major failure modes in the probabilistic structural assessment are explicitly explored with the consideration of soil spatial effect. This study points to the importance of addressing soil spatial effect to ensure design safety and robustness.
