Aiming at the difficult problems of numerous technologies and low standardization in the field of dam safety detection and monitoring in my country, this book carries out research on key technologies and engineering demonstrations of standardization of dam safety detection and monitoring technology through sorting out existing technical standards and investigating typical projects. The main contents are: proposing principles for selecting dam safety monitoring instruments, stipulating parameter requirements and validation methods for indoor inspection and on-site calibration of dam safety monitoring instruments; constructing a measurement system for safety monitoring systems, formulating technical routes for evaluation of dam safety monitoring systems, and establishing a comprehensive evaluation of dam safety monitoring systems. Multi-level fuzzy comprehensive evaluation method of price; proposed new principles for dividing water conservancy and hydropower project safety monitoring units, divisions and unit projects, improved the acceptance process for each stage of acceptance, refined safety monitoring instrument evaluation technical indicators, and formulated automation system acceptance assessment methods; research A method for constructing a dam safety appraisal parameter set was proposed, and the value standards and grading evaluation standards for dam safety appraisal parameters were proposed. The dam detection technology was sorted out, a dam safety monitoring index system was constructed, and a comprehensive evaluation method for dam safety detection based on multi-level fuzzy recognition theory was proposed. This book also provides many examples of safety inspection, monitoring and appraisal evaluation of typical water conservancy projects. The book is divided into 6 chapters. Chapter 1 is the introduction. Chapters 2 to 6 cover the selection and calibration standards of dam safety monitoring instruments, the measurement system and evaluation standards of dam safety monitoring systems, the acceptance methods and acceptance standards of dam safety monitoring systems, key technologies for standardization of dam safety appraisal parameters, and dam safety detection and evaluation technologies.
