Title: Uniaxial and triaxial compression test series on Topopah Spring tuff

Technical Report ·
OSTI ID:59478

Fifteen uniaxial and triaxial compression experiments were performed on samples of the Topopah Spring Member of the Paintbrush Tuff obtained from drill hole USW-G1 at Yucca Mountain on the Nevada Test Site. The water saturated test specimens were deformed at nominal strain rates of 10{sup -2}, 10{sup -4}, 10{sup -5} and 10{sup -6} s{sup -1}; confining pressures of 0.1, 5 and 10 MPa; and room temperature. Resultant unconfined compressive strengths, axial strains to failure, Young`s moduli and Poisson`s ratios ranged from 44.9 to 176.6 MPa, .0034 to .0057, 22.9 to 40.8 GPa and .15 to .33, respectively.
