G-Tunnel pressurized slot-testing data summary

Designers and analysts of radioactive waste repositories must be able to predict the mechanical behavior of the host rock. Sandia National Laboratories elected to conduct a development program to make mechanical measurements. The program was focused on pressurized slots testing and featured (1) development of an improved method to cut slots using a chain saw with a diamond tipped chain, (2) measurements useful for determining in situ stresses normal to slots, (3) measurements applicable for determining the in situ modulus of deformation parallel to a drift surface, and (4) evaluations of the methods and results of pressurized slot strength testing. This report provides the data summary for the last three activities
