ABSTRACT
A three-dimensional finite element structural analysis of the intersection of a typical disposal room and entryway drift at the WIPP has been performed. This analysis reveals how complicated underground openings, truly 3D in nature, respond in a creeping medium, and the response may appear anomalous to those with a “hard rock” background. Computed closures at the intersection are presented and compared to available in situ data. A qualitative agreement between measured and computed closures is seen.
