This book is intended as a reference book for advanced graduate students and research engineers in rock mechanics related to mining, civil engineering, etc. Rock mass is a kind of structural dependent material, and it is often exposed to complex stress disturbance, such as environmental and human-induced loading acting on rock that is cyclic in nature. Typical forms of stress disturbance include blasting vibration, earthquake, excavation, 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 rock structure on the dynamic disturbances engineering projects 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 cyclic and fatigue loading on rock is always vital to the rational design and the long-term stability prediction of rock constructions.
