Geomechanical Behaviors of Deeply Buried Rock under Triaxial Disturbed Stress Conditions by Yu Wang,Xuefeng Yi,Lei Yin Pdf

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.

Physico-Mechanical Properties and Treatment Technology of Hazardous Geomaterials, volume II by Xianze Cui,Bing Bai, Wenbin Fei Pdf

This Research Topic is Volume II of a series. The previous volume can be found here: Physico-Mechanical Properties and Treatment Technology of Hazardous Geomaterials New materials and technologies are emerging in every branch of geotechnical engineerings, such as high-speed railway subgrade, soil improvement and remediation, underground space structure, ground energy storage, energy pile, energy geostructure, energy tunnel, tunnel waterproof engineering, and marine engineering. In addition to the common infrastructure construction materials, it also includes the treatment of hazardous geomaterials, resource utilization of industrial wastes, geopolymer materials, contaminated soils related to geoenvironmental engineering as well as other newly developed materials. In recent years, the advancement of new materials has promoted the development of geotechnical engineering and its close intersection with other disciplines. Scholars have done fruitful work, but the understanding of many new materials is not very clear. Moreover, the external environment (e.g., heat, water, external force) borne by various materials is becoming more and more complex. The newly developed geotechnical materials involve the coupling actions of multiple fields such as physics, mechanics, chemistry and even biology. Some new technologies and specifications are still developing. For this purpose, it is necessary to investigate the mineral composition and micro-structures, physico-mechanical properties, deformation and strength evolution process, and constitutive characteristics of various geotechnical materials. The research methods include theoretical description, numerical simulation, laboratory experiments and field tests. The Research Topic aims to bring together Original Research and Review articles on the recent developments in natural geotechnical material improvement, hazardous geomaterials, synthetic materials, geopolymer, energy geotechnical materials and contaminated soil treatment.

Geological Disasters in Deep Engineering Mechanism, Warning and Risk mitigation by Guang-Liang Feng,Fengqiang Gong,Chi Zhang,Shibing Huang Pdf

With the increasing demand for infrastructure construction as the global economy progresses, the need for exploration and utilization of deep underground space becomes more crucial. Various deep underground projects are planned, are under construction, and have been built to encounter great construction challenges due to the complex geo-environment such as strong tectonic movement, fragile geo-environment and complex thermo-hydro-mechanical-chemical conditions. These deep engineering projects could be endangered by different kinds of geological disasters, such as intense rockburst, large deformation, strong water inrush, and large-scale collapse, which might result in massive loss of life and economic damage during the construction of deep underground projects. It is necessary to take proactive measures to ensure that the development of deep engineering projects is risk-informed and sustainable. Efforts are being called for strengthening science and technology innovation and cooperation in geological disaster mitigation and sustainable development during the construction of deep engineering projects. It is paramount to use new technologies and international cooperation to jointly tackle the geological disasters risks and achieve sustainable development. To mitigate the risk of geological disaster in deep engineering under the complicate geo-environment, the mechanism of the formation and evolution of geological disasters in deep engineering needs to be understood. The testing, monitoring, simulation, risk assessment and early warning methods for geological disaster in deep engineering are also needed urgently. New theories, methods and techniques related to the mechanism, warning and risk mitigation of geological disasters in deep engineering will be extremely helpful for the construction safety of deep engineering.
