岩石斷裂的萌生和擴展是引起岩石結構破壞的主要原因，因此，岩石斷裂過程的詳細觀測為岩石力學和岩石工程提供了幫助。然而，岩石斷裂力學存在兩個基本的困難：一是難以對岩石斷裂進行全面、準確、細致的觀察；二是難以進行復雜條件下岩石斷裂過程的實驗模擬。《岩石斷裂力學：斷裂過程可視化、分析及應用》應用數字圖像相關(DIC)的光學技術來研究岩石破裂過程和相關的應用。為了模擬原位岩石工程的復雜情況，《岩石斷裂力學：斷裂過程可視化、分析及應用》給出了三個重點：模式I、混合模式和模式II載荷下的斷裂過程。《岩石斷裂力學：斷裂過程可視化、分析及應用》分為5個章。第1章介紹聲發射技術及其相關技術；第2章闡述不同加載方式下的岩石斷裂過程；第3章主要研究岩石在壓縮作用下的斷裂過程；第4章介紹熱效應對岩石破裂過程的工程應用；第5章介紹一種特殊的工程應用：哈克岩石隧道的剝落過程。
