Abstract

A risk-based standardized management system of dike engineering is established by integrating the risk management theory with the work, technology, management and evaluation standardized systems of dike engineering. A risk assessment approach for the standardized management system is also proposed. The key dike projects in the Poyang Lake area are taken as typical cases. The standard maps of life, economic and environmental risks of dike engineering in China are determined at first. Subsequently, the risk matrix method is adopted to compute the assessment index coefficients for the life, economic and social environmental risks, respectively, and estimate the comprehensive assessment index coefficient. The risk-based standardized management scores of dike engineering are obtained through incorporating the comprehensive assessment index coefficient into the standardized evaluation management. Finally, the scores are used to evaluate whether the standardized management of dike engineering is qualified. The results indicate that the established standardized management system of dike engineering provides not only theoretical and technical supports for working out the scientific and rational failure risk management decisions and measures for dikes, but also references for operation management of other dike projects.
