【 摘 要 】

This report was prepared for presentation at the STRATCOM Advanced Concept Technology Demonstration (ACTD) meeting held in Albuquerque, New Mexico, May 21, 2003. It discusses the methods that can be used to estimate the mechanical properties of rock masses, such as deformability and strength. Special emphasis is put on the fact that rock mass properties are subject to an effect of scale, i.e. the properties measured on laboratory-scale samples are not representative of in-situ properties because of the presence of geologic discontinuities. This information is relevant to the planning of new field tests to assess the effects of explosions in the ground that are part of the on-going ACTD.
