GENERATION OF STRONG GROUND MOTION AT THE NEVADA TEST SITE FOR SEISMIC TESTING OF FULL-SCALE STRUCTURES

摘要

The Nevada Testing Institute (NeTI) and SRI International with support from Bechtel Corporation, Bechtel Nevada, Lawrence Livermore National Laboratory (LLNL), Department of Energy (DOE) Nevada Operations Office, and the Defense Threat Reduction Agency (DTRA) are developing a full-scale strong ground motion testing facility at the Nevada Test Site (NTS), referred to as the Nevada Seismic Testing Center. SRI developed the Repeatable Earth Shaking by Controlled Underground Expansion (RESCUE) technique for producing strong ground motion through funding from the National Science Foundation (NSF). The RESCUE technique has been optimized and demonstrated through numerous finite element computations and tests performed by SRI, LLNL, and Bechtel Corp. This paper presents results from computations and 1/7-scale prototype tests performed at NTS that indicate the full-scale facility will produce horizontal ground accelerations of 1 to 2 g's, velocities of 100 to 140cm/s, and displacements of 60 to 100cm.
