Today, the sluice plays important roles in many fields, such as flood control, water supply, shipping, power generation, drainage, aquaculture, tourism, ecological environmental protection, and so on. However, because of the long-term load and environmental effects and inadequate management, there are a lot of serious potential safety hazards for many sluices. In order to eliminate sluice diseases and recovery the original designed function of the sluices a large number of sluice reinforcement works have been conducted in recent years in China. As the basic and important work, the safety evaluation of the sluices has been paid more attention to nationwide. Therefore, based on the research achievements, the security identification technology was studied combining with the specific circumstances of the sluices. The main contents include:(1) Referring to the relevant standards and specifications, the content of safety appraisal, procedure and safety grade standard in China were summed up. The compo
