Operations NOUGAT and STORAX in Situ Stresses in Rock, Rainier Mesa, Nevada Test Site,
Abstract
This investigation was made at the recommendation of the Lawrence Radiation Laboratory and funded by the Atomic Energy Commission under Memorandum of Understanding AT(29-2)-914, dated 14 September 1959 and amended by Modifications 9, December 1963. The objectives of this investigation were: (1) To perform surveillance of the stress measurement made by Lucius Pitkin, Inc. (LPI), New York City, in Tunnels G, B, E, P, and N, Madison and Yuba Events; (2) To determine the mechanical properties of the rock from the tunnel sites specified in (1); (3) To analyze the results obtained in (1) and (2) and to prepare interim and summary reports. The Lawrence Radiation Laboratory's interest in this investigation was specified in a telegram to L. Obert, O. H. Roehlke, and W. P. Bennett from J. E. Carothers, LRL, dated 12 September 1962, which stated that, 'LRL's interest in measurements of overburden stresses with the APRL technique in our tunnels is to determine preshot conditions in the rock surrounding the shot rooms and at the massive concrete plugs. In the explosion of a nuclear device the cavity presumably grows until the pressure within the cavity falls to the overburden pressure.
