摘要

Analyses, both mathematical and experimental, are developed to assist in the rational design of subterranean instrumentation cables that must survive pressures of two to three kbars, large axial strains of the order of 40 percent, and severe shear offsets, to allow the measurement of late-time displacements induced by large explosions. Reports on underground tests and other pertinent literature are reviewed and analyzed for the purpose of documenting the design of instrumentation cables, the performance of cables, and cable problem areas. Both past and current cable practices are also documented from discussions on cable techniques with experimenters involved in the fielding of underground tests. The state-of-the-art in subterranean instrumentation cable design is set forth. Uncertainties both in current design procedures and in the performance of hardware components are pointed out. The review indicates that no proven technique is currently available for providing reliable data transmission in the large strain, high pressure environment imposed by an underground nuclear test. A program to advance the state-of-the-art, which emphasizes logical design, analysis, and experimental tests, is laid out. (Author)
