This book has following unique features that distinguish it from other works from the same area: 1) Investigates the influence of fissure geometry on strength failure and crack evolution behaviour of real rock material; 2) Analyzes the effect of pre-experiment high-temperature treatment on fracture mechanical behaviour of rock material with a single fissure or two parallel fissures; 3) Compares quantitatively simulated results using discrete element modelling and experimental results of fracture mechanical behaviour of rock material with two fissures; 4) Constructs the relationship between crack evolution processes and acoustic emission distribution of pre-fissured rock material under entire deformation; and 5) Discusses the crack evolution mechanism of pre-fissured rock material with respect to different confining pressures. This book can become the reference for technicians in the field of geotechnical engineering, mining engineering and geology engineering. At the same time, this book can be regarded as a good reference for scientific researchers carrying out fissured rock mechanics and correlated specialties.

Dr. Sheng-Qi Yang was born in December, 1978. In 2003, he started his Ph.D research, in Hohai University, Nanjing, P.R.China, and got Geotechnical Engineering of Doctor's degree in April, 2006. In 2007-2008, he continued his post-doctoral work in Ecole Polytechnique de Paris, France. In 2014-2015, he obtained an Endeavour Research Fellowship in Australia, and commenced his research in the department of civil engineering, Monash University as a visiting professor. From 2012, he has been promoted a full Professor and a PhD supervisor in China University of Mining and Technology. In March, 2014, he was elected an assistant director of State key Laboratory for Geomechanics and Deep Underground Engineering.In 2013, he was awarded the Program for New Century Excellent Talents in University from Ministry of Education. He obtained the Youth Science and Technology award from Chinese Society for Rock Mechanics and Engineering and Sunyueqi Foundation Council. In 2011, he also obtained the Second Prize of Science and Technology Progress from Ministry of Education. In the past five years, he takes charge of more than ten key scientific projects including 3 National Natural Science Foundation of China (NSFC). His research interests focus mainly on deep fissured and jointed rock mechanics; rock creep (time-dependent) experimental and model mechanics; and deep underground rock mass engineering and reinforced technique.To date, Professor Sheng-Qi Yang has published one Chinese book with the title "Study on the mechanical behavior of fissured rock and its time-dependent effect analysis" (Beijing: Science Press, 2011). He has also published about 80 papers, in which more than 20 English papers (indexed by SCI) were published in International Journal of Rock Mechanics and Mining Sciences, Rock Mechanics and Rock Engineering, Tunneling and Underground Space Technology, Journal of Structural Geology, Engineering Geology, International Journal of Fracture, Engineering Fracture Mechanics, Canadian Geotechnical Journal, etc. He has applied for 10 national invented patents, in which three patents has been awarded. He is the Editorial board of two journals "The Scientific World Journal" and "Journal of Basic Science and Engineering". He has also made six lectures in some important academic conferences, e.g. 2014 International Symposium on Soft Rock.
