Material Properties of Nevada Test Site Tuff and Grout - with Emphasis on the Mighty Epic Event
The primary task during this period was material evaluations for the Mighty Epic event (both preshot and postshot). Tuff, grout, sand, concrete, concrete-steel interfaces and steel were tested. Other material evaluations and analyses during this period were for (1) the two-in-one concept -- a proposed plan to use a common tunnel and equipment for two nuclear events, (2) determining the influence of fracturing on ultrasonic velocities to help explain field seismic and sonic velocity results, (3) obtaining the angles-of-internal-friction in the tuff as a function of confining pressure for use in material modeling, (4) determining and evaluating methods for extracting pore water for subsequent chemical analysis, (5) measuring the effect of hydrostatic pressure (i.e. grain size distributions, cohesion, etc.) on sand-water mixtures, (6) evaluating currently used and proposed methods for obtaining the elastic moduli needed to determine in situ stress from tuff overcore samples, and (7) evaluating the possibility of resaturating dry tuff core samples for obtaining material properties representative of the original saturated material and for evaluating the likelihood of water invasion into core samples during the field coring process.
