内容简介：
岩石断裂的萌生和扩展是引起岩石结构破坏的主要原因，因此，岩石断裂过程的详细观测为岩石力学和岩石工程提供了帮助。然而，岩石断裂力学存在两个基本的困难：一是难以对岩石断裂进行全面、准确、细致的观察；二是难以进行复杂条件下岩石断裂过程的实验模拟。岩石断裂力学：断裂过程可视化、分析及应用应用数字图像相关(dic)的光学技术来研究岩石破裂过程和相关的应用。为了模拟原位岩石工程的复杂情况，岩石断裂力学：断裂过程可视化、分析及应用给出了三个重点：模式i、混合模式和模式ii载荷下的断裂过程。岩石断裂力学：断裂过程可视化、分析及应用分为5个章。章介绍声发技术及其相关技术；第2章阐述不同加载方式下的岩石断裂过程；第3章主要研究岩石在压缩作用下的断裂过程；第4章介绍热效应对岩石破裂过程的工程应用；第5章介绍一种特殊的工程应用：哈克岩石隧道的剥落过程。
