FINITE ELEMENT MODELING OF SETTLEMENTS ON SPATIALLY RANDOM SOIL. TECHNICAL NOTE
The authors of this technical note studied the effect of a random and spatially correlated soil stiffness on the total settlement under the center of a uniformly loaded flexible-strip footing. Random field theory was combined with the finite-element method to conduct Monte Carlo simulations of the settlement problem with a variable Young's modulus and a constant Poisson's ratio. The local average subdivision (LAS) method was used to simulate the soil Young's modulus field with a fixed mean, standard deviation, and spatial correlation structure. Parametric study results were compared to deterministic quantities to gauge the effect of the standard deviation, correlation structure, and geometry on the settlement behavior. The results reveal a modest increase in expected settlement for presumptive ranges of soil stiffness variability.
