On-site Inspection and Dam Safety Evaluation (Hydroscience and Engineering)

Practice has proven that conducting safety evaluations of reservoir dams has become a necessary measure to ensure the safety of water conservancy projects. This book introduces the development and achievements in the safety management of reservoir dams in China. Each chapter systematically sorts out and integrates evaluation measures related to different stages of the entire life cycle of reservoir dams, including planning, design, construction, operation and maintenance, repair and reinforcement, and decommissioning or removal, forming a complete dam safety evaluation management system.

This book emphasizes the importance of conducting on-site inspections for dam safety management. A differentiated safety evaluation method and disposal strategy have been proposed for different engineering scales, management levels, and risk levels, making the technical route of safety evaluation more reasonable and operable. The book is written as a reference book for professional engineers and is also suitable for post graduate courses.

She has led and participated in multiple scientific research projects, including the National Key Research and Development Program of China " Key technologies and applications of safety diagnosis and smart management of reservoir dams", the National Natural Science Foundation of China's "Research on the Impact of Overextraction of Groundwater on Near Surface Heat Island Effect", the National Natural Science Foundation of China's "Research on the Response of Unsaturated Water Flow and Pollution to Vertical Cracks", and the Yunnan Provincial Science and Technology Plan project "Construction of a Benign Operation Management Model for Water Conservancy Engineering in Yunnan Province". She has published over 30 papers, and authorized more than 10 nation invention patents.

Prof. Chengdong Liu works at the Dam Safety Management Department of Nanjing Hydraulic Research Institute, mainly engaged in research on reservoir dam safety evaluation, safety monitoring and early warning, and informatization and intelligent management of water conservancy projects. He has led and participated in multiple scientific research projects such as the National Key Research and Development Program of China and National Natural Science Foundation of China. He has also led and completed the research on dam safety evaluation, preparatory emergency plans, dam safety monitoring, and information systems for more than 100 large-sized and medium-sized reservoirs, including the Xiaolangdi Hydro-Junction, Danjiangkou Reservoir, Siminghu Reservoir, and Heilongtan Reservoir. He is one of the lead authors of National Sector Standards including Guidelines on dam safety evaluation, Technical specifications for real-time automatic monitoring and early warning system of termites in water conservancy and hydropower projects, and so on. Liu was selected as a top notch talents in the "Kunlun Talent · High-end Innovation and Entrepreneurship Talent Project" in Qinghai Province in 2020. He has published over 50 academic papers and published 5 books.

Zhang Kai is currently working in the Dam Safety Management Department of Nanjing Hydraulic Research Institute, and has long been engaged in the research of reservoir dam safety evaluation, and deep-water hazard detection. As the project leader, he has completed the safety evaluation of more than 40 large and medium-sized reservoirs, and participated as a technical backbone in the emergency response of 5 reservoir dams. He has presided over the research and development of the "intelligent support cloud platform for reservoir dam safety appraisal", which has been applied in the safety appraisal of nearly 50 reservoirs and dams, and has rich experience in the diagnosis and assessment of reservoir dam safety. He has developed a complete set of technology for underwater inspection and performance evaluation of long-distance culverts, which has been successfully applied to the underwater inspection of more than ten water conservancy projects. He has published 15 papers (including 1 SCI-indexed paper) and holds 7 authorized invention patents.
