Abstract:

The objective of this investigation was to determine the influence of pore water pressure on the engineering properties of rock. A series of drained triaxial compression tests were performed on Vermont marble in order to study strain rate effects. Isotropic compression and triaxial compression tests under drained and undrained conditions were performed on Berea sandstone, Salem limestone, Vermont marble, and Barre granite. The drained and undrained tests resulted in a single Mohr-Coulomb failure envelope in terms of effective stress for each rock type. In all cases the failure envelope was concave to the normal stress axis. The modified Mohr-Coulomb failure envelope plotted as a straight line for each rock type.
