Abstract

Joints often have a significant influence on material characteristics. The discontinuities’ coalescence mechanism and complex jointed rock mass structure as a composite need to be further explored. In this study, compression and shear tests were carried out on a jointed rock mass. The purpose of the jointed rock mass behaviour study was to determine the deformation-strength dependencies and to determine the parameters for a quantitative assessment of the joints’ influence on mechanical characteristics. The results show that compression strength depends on the materials’ structure, and there is a detailed description of the joints’ orientation influence on stress-strain dependencies during compression experiments. The numerical method used in this study could be used for the modelling of composite materials and their properties.

三维应力场中节理岩体各向异性的实验与数值研究

接头通常对材料特性有重大影响。结构面聚结机制与复杂节理岩体结构作为一个整体需要进一步探讨。在本研究中，对节理岩体进行了压剪试验。节理岩体行为研究的目的是确定变形强度依赖关系，并确定节理对力学特性影响的定量评估参数。结果表明，材料的抗压强度取决于材料的结构，并详细描述了接头方向对压缩试验中应力-应变依赖关系的影响。本文所采用的数值方法可用于复合材料及其性能的模拟。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
