Download or read book Coupled DEM CFD Analyses of Landslide Induced Debris Flows written by Tao Zhao and published by Springer. This book was released on 2017-05-22 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reflects the latest research results in computer modelling of landslide-induced debris flows. The book establishes an understanding of the initiation and propagation mechanisms of landslides by means of numerical simulations, so that mitigation strategies to reduce the long-term losses from landslide hazards can be devised. In this context, the book employs the Discrete Element Method (DEM) and Computational Fluid Dynamics (CFD) to investigate the mechanical and hydraulic behaviour of granular materials involved in landslides – an approach that yields meaningful insights into the flow mechanisms, concerning e.g. the mobilization of sediments, the generation and dissipation of excess pore water pressures, and the evolution of effective stresses. As such, the book provides valuable information, useful methods and robust numerical tools that can be successfully applied in the field of debris flow research.

Download or read book Coupled Thermo Hydro Mechanical Processes in Fractured Rock Masses written by Fengshou Zhang and published by Springer Nature. This book was released on 2023-09-11 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: The subject of thermo-hydro-mechanical coupled processes in fractured rock masses has close relevance to energy-related deep earth engineering activities, such as enhanced geothermal systems, geological disposal of radioactive waste, sequestration of CO2, long-term disposal of waste water and recovery of hydrocarbons from unconventional reservoirs. Despite great efforts by engineers and researchers, comprehensive understanding of the thermo-hydro-mechanical coupled processes in fractured rock mass remains a great challenge. The discrete element method (DEM), originally developed by Dr. Peter Cundall, has become widely used for the modeling of a rock mass, including its deformation, damage, fracturing and stability. DEM modeling of the coupled thermo-hydro-mechanical processes in fractured rock masses can provide some unique insights, to say the least, for better understanding of those complex issues. The authors of this book have participated in various projects involving DEM modeling of coupled thermo-hydro-mechanical processes during treatment of a rock mass by fluid injection and/or extraction and have provided consulting services to some of the largest oil-and-gas companies in the world. The breadth and depth of our engineering expertise are reflected by its successful applications in the major unconventional plays in the world, including Permian, Marcellus, Bakken, Eagle Ford, Horn River, Chicontepec, Sichuan, Ordos and many more. The unique combination of the state-of-the-art numerical modeling techniques with state-of-the-practice engineering applications makes the presented material relevant and valuable for engineering practice. We believe that it is beneficial to share the advances on this subject and promote some further development.

This book was released on 2024-01-29 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the beginning of the 21st century, global environmental problems have become increasingly prominent, and extreme weather events have become more frequent. The irrational development and excessive construction of underground space have also led to various disasters, such as landslides, collapses, debris flows, and ground collapses. According to the data released in the National Geological Disaster Bulletin, 133899 geological disasters have occurred in China from 2009 to 2019, of which landslides accounted for 71%, collapses for 19%, and debris flows for 8%, and ground collapses for 2%. The number of casualties and economic losses caused by rock and soil disasters are the greatest in the world. Therefore, a good understanding of disaster-causing mechanisms of rock and soil has a strong theoretical and practical significance for the safe construction of diversified geotechnical projects.

Download or read book Debris Flow written by G. Lorenzini and published by WIT Press. This book was released on 2004-02-05 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: Debris flows are among the most frequent and destructive of all geomorphic processes, mainly affecting mountainous areas in a range of morphoclimatic environments, and the damage they cause is often devastating. Increased anthropisation calls for improvements in the criteria used to identify debris-flow risk areas and the prevention measures adopted. One of the main difficulties encountered by the approaches illustrated in previous literature is linked to their possible validation either in the field or in a laboratory environment. The choice of a rheological model is extremely important. This book provides methodological details, which can be applied to investigations on debris-flow mechanics, capable of providing an accurate representation of the phenomenology.
Download or read book Prevention Mitigation and Relief of Compound and Chained Natural Hazards written by Chong Xu and published by Frontiers Media SA. This book was released on 2024-08-21 with total page 129 pages. Available in PDF, EPUB and Kindle. Book excerpt: At present, the intensification of global climate and environmental change has led to frequent occurrence of natural hazards. Various types of natural hazards always overlap and interact, or occur in a chain reaction, with a wide range of impacts and a long period of time, resulting in serious disaster losses. Typically, major earthquakes and geological hazards, extreme meteorological hazards, large-scale floods and droughts, marine disasters, and forest and grassland fires, as well as their compound and chained hazards are among the key factors affecting human life safety and world economic development. To better our understanding of disaster prevention, mitigation, and relief, it is thus pivotal to facilitate advanced perception, intelligent early warning, accurate prevention, and efficient rescue of natural hazards. This Research Topic aims to collect both Original Research and Review articles addressing the state-of-the-art advances of theories and methodologies in all types of natural hazards. Studies underlining the compound and chained relationship between different hazards are in particular welcomed. Potential themes include, but are not limited to: • Mechanisms of formation, evolution, and disaster process of multiple natural hazards as well as their compound and chained natural hazards • Model and scenario development regarding whole process control, chain breaking of key nodes, and precise prevention of major natural hazard chains • Methods and applications on detection, identification, database establishment, and spatiotemporal evolution law analysis of natural hazard sources • Technologies on intelligent early warning and refined risk assessment of compound and chained natural hazards. • Rescue equipment and investigation of post-disaster community reconstruction

This book was released on 2007-05-17 with total page 659 pages. Available in PDF, EPUB and Kindle. Book excerpt: Amongst the thematic topics discussed are global frequency, impacts on society, analysis of initial rock slope failure, monitoring of rock slope movement, analysis and modeling of post-failure behaviour, volcanic landslides, and influences of massive rock slope failure on the geomorphological evolution of mountain regions. Regional contributions include reports on rockslides and rock avalanches in Norway, western Canada, the Andes of Argentina, the Karakoram Himalaya, the European Alps, the Appennines, and the mountains of Central Asia. Rockslides and rock avalanches in the Central Asian republics of the former Soviet Union are discussed in detail for the first time in an English-language book. These landslides include the 1911 Usoi rockslide, that dammed 75 km-long Lake Sarez, and the 1949 Khait rock avalanche that may have killed up to 28,000 people. Both landslides were earthquake-triggered and both are located in Tajikistan. An additional highlight is a detailed description and analysis of large-scale artificial rock avalanches triggered by underground nuclear explosions during the testing programme of the former Soviet Union.
