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.
