This work involved the response of a liner-bolt system installed on the wall of the DIAMOND FORTUNE cavity, a 22-m diameter nearly semi-spherical chamber in tuff, at the Nevada Test Site. DIAMOND FORTUNE is a low-yield nuclear test of the Defense Nuclear Agency which was performed in April, 1992. A 1.4-m square, 2.5-cm thick steel plate was anchored by 9-m long bolts: four 2.5-cm diameter bolts at the comers and a 5-cm diameter bolt at the center. The bolt ends daylighted in a tunnel surrounding the cavity, and were tensioned from there. The system was aped with 20 data channels for strain, acceleration, contact pressure, and temperature. We relate the thermal analyses and the 3-dimensional dynamic analyses performed for this project, and we present the test results which indicated the excellent response of this system to the high dynamic loads and temperatures.
