The report documents the results of a limited number of static and dynamic tests on one tuff from the location of the Diamond Mine Event tunnel at the Nevada Test Site. The tests comprised the first experimental study conducted in the then newly developed dynamic high-pressure triaxial test device. The purpose of the study was to determine loading rate effects on the uniaxial strain, hydrostatic compression, and triaxial shear response of that tuff when loaded statically (approximately 2 minutes to peak stress) and dynamically (approximately 20 msec to peak stress). The results indicated that rate effects were of secondary importance when compared with the effects of variation of water content of specimens. Primary consideration should be given to testing the tuff at its in situ water content. (Author).
The report documents a study conducted on the Gulf Radiation Technology (GRT) piezoelectric stress gage in support of the Diamond Mine Event at the Nevada Test Site (NTS). The gage was first calibrated in oil and then embedded in an NTS grout and tested under conditions of uniaxial strain. The results of these tests indicated a slightly nonlinear output of the gage under hydrostatic loadings and an under registration of the gage when embedded in the grout. Limited uniaxial strain tests were concurrently conducted on the grout mix. The property information from these tests was used as input to the WESTES finite element code in which the test boundary conditions were simulated to analytically investigate behavior of the grout specimen with and without an embedded inclusion or gage. The calculated results indicated that the contact interface between the gage and the grout had the greatest effect on gage performance. (Author).
