Abstract: In order to improve the perception ability of water project safety risk, based on a comprehensive analysis of impacts of geographic climate, topographical geology, structural material and project operation on the safety risks of specific water project, the risk perception is divided into four levels: input (impact) factor perception, output (effect) perception, structure and basic state perception and follow-up perception. The corresponding relationship between these four levels and existing safety monitoring or detection items is analyzed. According to the requirements of risk management, the low security risk project only needs to set input perception. With the increase of safety risk, the perception level is gradually increased. All four levels of perception need to be set for the high-risk water project. And then a multi-level dynamic risk perception system suitable for different risk levels and their dynamic evolution can be established. The system proposed in this paper realizes the integration of safety monitoring and detection, which is helpful to unify the theoretical basis of monitoring and detection item setting for different structures and their different working stages, and has certain significance for improving the ability of early warning of safety risks in water project.
