dc.descriptionAbstract: 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 Station's new dynamic high-pressure triaxial test device. Although the test program was very limited, the test data do provide some insight into the hydrostatic and shear response o:f the tuff materials tested. The test data indicate some of the material did exhibit loading-rate effects and there were differences in the response characteristics of the specimens from the two tunnels as well as differences in the response characteristics of different specimens from one of the tunnels.-
