一般来说,在岩体中裂隙和节理的分布是十分复杂的。存在的这种不连续面对岩体的强度和变形等性能影响很大,例如,有裂隙分布的岩体的破裂,可能逐渐趋于稳定或呈现瞬时不稳定破裂,这很大程度上取决于这些不连续面的分布。此外,构成岩体的完整块石具有很大变动的特性,可以从应变硬化到应变软化。本文重点讨论裂隙扩散,应变软化的特性以及膨胀等不同形式试验的成果。同时,由试验结果研究岩体的本构关系。
In general, the distribution of cracks and joints in rock masses is very complicated. The existence of such discontinuities has great influence on the strength and deformation of rock masses. For example, fractured rock masses may gradually stabilize or exhibit transient instability fractures, depending largely on The distribution of these discontinuities. In addition, the complete block rock that constitutes the rock mass has very variable characteristics that can range from strain hardening to strain softening. This paper focuses on the results of crack propagation, strain softening, and expansion and other forms of testing. At the same time, the constitutive relations of rock masses were studied from the results of the tests.
