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.

The charm of Mathematical Physics resides in the conceptual difficulty of understanding why the language of Mathematics is so appropriate to formulate the laws of Physics and to make precise predictions. Citing Eugene Wigner, this “unreasonable appropriateness of Mathematics in the Natural Sciences” emerged soon at the beginning of the scientific thought and was splendidly depicted by the words of Galileo: “The grand book, the Universe, is written in the language of Mathematics.” In this marriage, what Bertrand Russell called the supreme beauty, cold and austere, of Mathematics complements the supreme beauty, warm and engaging, of Physics. This book, which consists of nine articles, gives a flavor of these beauties and covers an ample range of mathematical subjects that play a relevant role in the study of physics and engineering. This range includes the study of free probability measures associated with p-adic number fields, non-commutative measures of quantum discord, non-linear Schrödinger equation analysis, spectral operators related to holomorphic extensions of series expansions, Gibbs phenomenon, deformed wave equation analysis, and optimization methods in the numerical study of material properties.

This book presents mainly experimental studies on the mechanical behavior and damage fracture mechanism of deep rocks including sandstone, marble, mudstone and granite, combining with several advanced technologies of X-ray micro-CT and AE monitoring. It has several unique features: 1) Investigates the influence of loading path on triaxial strength and deformation behavior of sandstone and marble; 2) Analyzes the effect of borehole size on triaxial strength and deformation behavior of hollow sandstone; 3) Explores the influence of high temperature on triaxial deformation and permeability behavior of sandstone and granite; 4) to reveal the damage fracture mechanism of deep rocks using spatial AE techniques and X-ray micro CT observations. This work will appeal to a wide readership from technicians in the field of geotechnical engineering and engineering geology to scholars carrying out research in the rock mechanics.

Discontinuities such as cracks, fissures, bedding planes, etc. resulting from different geological processes are commonly found in rock masses and often play a critical role in the initiation, propagation, and coalescence of new cracks due to stress redistribution caused by engineering activities and natural disturbances. It is challenging to determine the instability mechanism of jointed rock masses but it is vital for estimating instability disasters in jointed rock engineering.

Rock Dynamics – Experiments, Theories and Applications is a collection of scientific and technical papers presented at the Third International Conference on Rock Dynamics and Applications (RocDyn-3, Trondheim, Norway, 26-27 June 2018). The papers in the book reflect the recent developments in experiment and theory as well as engineering applications of rock dynamics. Rock dynamics studies the response of rock and rock masses under dynamic loading and during the state transition from static loading to kinetic movement. It also includes the study of engineering countermeasures to dynamic instability of rock and rock masses. The topics in the book include: - Dynamic theories - Numerical simulation - Propagation of stress waves - Dynamic tests of rock - Stability of underground openings under dynamic loading - Rockburst - Seismic monitoring - Dynamic rock support - Blasting - Earthquake-related rock structure damage, etc. Applications, such as rockburst, dynamic rock support, seismic monitoring, blasting and earthquake-related rock structure damage, are paid special attention in Rock Dynamics – Experiments, Theories and Applications. The papers, from specialists both from mining and tunnelling branches, discuss commonly interested dynamic issues. Their experience and knowledge in the application of rock dynamics are extremely valuable for all academics, engineers and professionals who work with rock dynamics.

This book is intended as a reference book for advanced graduate students and research engineers in rock mechanics related to civil, mining, hydropower, and traffic engineering, etc. For rock mass during construction, they are often subjected to complicated stress disturbance conditions, such as human-induced and environmental loading acting on rock that is cyclic or fatigue in nature. Typical forms of stress disturbance include excavation unloading, blasting vibration, earthquake, drilling and vehicle loading, etc. Usually, the stress disturbance condition is inferred as a kind of dynamic loading and differs dramatically from those under static loads. Along with the constructions on rock mass, a lot of disasters, e.g., tunnel rockburst, induced seismicity and sand liquefaction, are cyclic and dynamic processes. Nevertheless, insufficient attentions have been paid to the influences of disturbed stress on the long-term stability of rock mass construction so far. The discrepancy between theoretical prediction (by approximating the dynamic problems as static ones) and actual performance of constructed engineering structures is usually tolerated. As a result, investigation of the disturbed stress on rock is always vital to the rational design and the long-term stability prediction of rock constructions.
