A limited laboratory testing program was conducted on materials cored from two tunnels at the Nevada Test Site, Mercury, Nevada. The materials were grouped into three different tuffs. The purposes of the study were to investigate the loading-rate effects and the response characteristics of the materials from the two tunnels. Both static rise time of approximately 1 minute and dynamic rise time of 2 to 50 msec hydrostatic and triaxial shear tests were conducted in the U. S. Army Engineer Waterways Experiment Stations new dynamic high-pressure triaxial test device. Although the test program was very limited, the test data to provide some insight into the hydrostatic and shear response of the tuff materials tested.
