Abstract

The purpose of the numerical analysis effort of Task 27 of cooperative agreement DE-FC08-98NV12081 was to investigate the effect of lithophysal porosity on the elastic stress-strain properties of the tuff rock mass. Rock mass properties without lithophysal cavities are designated matrix properties. Rock mass properties with lithophysal cavities are designated effective properties. The analysis will be performed for a 6" by 6" square cross-section with a uniform distribution of lithophysal cavities for a variety of porosities. The analyses will be performed using FLAG 2D version 3.5, a Department of Energy qualified software. The analyses will compare the matrix properties to the effective properties.
