Damage is a fundamental component of rock failure from the micro-to the macro-scale. The proposed research seeks to develop new methods of characterizing rock damage applicable to laboratory samples, high rock slopes and underground excavations. A major focus of the research will be the extension of discrete fracture network engineering, DFNE concepts of crack intensity, crack connectivity, focused and distributed damage and critical connectivity relationships to practical rock engineering solutions. Laboratory compression and indirect tensile testing will be undertaken on a wide variety of rock types illustrating varying mineralogy and microstructure with monitoring using conventional methods and a wide range of NDT

从微观到宏观，损伤都是岩石破坏的基本组成部分。这项拟议的研究旨在开发适用于实验室样本、高岩坡和地下挖掘的岩石损伤特征的新方法。研究的主要重点将是将离散裂缝网络工程、裂缝强度、裂缝连通性、集中和分布损伤以及临界连通性关系的DFNE概念扩展到实际的岩石工程解决方案。将对各种岩石类型进行实验室压缩和间接拉伸测试，说明不同的矿物学和微观结构，并使用常规方法和广泛的无损检测进行监测
