Abstract
Describes a set of numerical techniques which implement the rate-depen dent multi-mechanism deformation (M-D) constitutive model for rock sal t in a finite element code for use in three-dimensional, finite strain simulations of creep closure in deeply buried salt excavations. Prese nts essential details of the numerical implementation. The constitutiv e model is exercised in a three-dimensional closure simulation of a la rge underground field experiment. Compares results from the simulation against actual closure measurements taken from the experiment.
