Analysis and safety evaluation of large-scale irrigation area projects in China

Large-scale irrigation area projects have long water transmission lines, a huge number of various hydraulic structures, and backbone projects, some of which are in serious disrepair. Some irrigation area projects are often in a state of illness or extended service, and the safety situation is not optimistic. On the basis of introducing the safety status of large-scale irrigation area projects in China, the research status of risk source identification, safety evaluation, reinforcement and reconstruction in large-scale irrigation area projects are emphatically discussed, and the development trend and existing problems of engineering safety management mode in large-scale irrigation area projects are summarized. It is considered that in the future, in-depth research should be made on risk identification and control technology, damage evolution of building concrete under service conditions, risk management and control mechanism, digital and intelligent management, etc., so as to ensure the safe and long-term operation of large-scale irrigation area projects.
