Abstract

Abstract A stochastic method and its computer implementation to evaluate the earth structure settlements that occur under static loading is presented in this paper. The settlements are calculated with a commercial finite difference program called Dynard, which considers a non-linear elasto-plastic soil model based on the shear and bulk moduli and the undrained strength of the soil. The Monte Carlo simulation technique and the Rosenblueth's point estimate methods are considered in the proposed approach. To illustrate the suitability and accuracy of the proposed procedure, the settlements arising on an earth dam model under gravity loads are calculated. The results are compared and validated with the settlements obtained with a boundary element method program codified by the authors.
