Sluice safety reliability analysis - Application for Baovan sluice in Vietnam

Abstract

The article summarizes the irrigation works designing methods in Vietnam and other countries. While in Vietnamirrigation systemdesign method is deterministic and based on safety factors analysis, in other countries it’s popular with random design and reliability analysis. This is a modern design model and widely used in many fields in the world. Therefore, in this study, the authors presented how to develop sluice reliability calculation method under system analysis approach: definition of sluice s, problem tree, reliability functions for system simulation, calculation of reliability for works and works system, calculate reliability Bao Van sluice in Thanh Hoa province according to the introduced calculation model and proposie solutions to improve the reliability of the sluice if repaired or upgraded.
