岩石块包含互锁的角碎片或硬脆性材料的块，这些材料被不连续的表面隔开，这些材料可能与较弱的材料覆盖，也可能不会涂有较弱的材料。这种岩石质量的强度取决于完整的碎片的强度以及它们的运动自由，进而取决于不连续性的数量，方向，间距和剪切强度。对此问题的完整理解提出了令人难以置信的理论和经验问题，因此需要简化假设，以便为估算工程设计目的的估算岩石质量的强度提供合理的基础。本文总结了可以做出这种简化假设的一些基本信息。提出了一个简单的经验故障标准，并通过许多实践示例说明了其在工程设计中的应用。 des asses de Rochers comprennent des des颗粒Angulailes anchevetrees out des ...
Jointed rock masses comprise interlocking angular par- ticles or blocks of hard brittle material separated by discontinuity surfaces which may or may not be coated with weaker materials. The strength of such rock masses depends on the strength of the intact pieces and on their freedom of movement which, in turn, depends on the number, orientation, spacing and shear strength of the discontinuities. A complete understanding of this problem presents formidable theoretical and experi- mental problems and, hence, simplifying assumptions are required in order to provide a reasonable basis for estimating the strength of jointed rock masses for engineering design purposes. This Paper summarizes some of the basic information upon which such simplifying assumptions can be made. A simple empirical failure criterion is presented and its application in engineering design is illustrated by means of a number of practical examples.
