摘要: |
大型灌区输水线路长,建筑物数量庞大且种类繁多,部分骨干工程老化失修严重,一些灌区往往处于带病或超期服役状态,安全状况不容乐观。在介绍我国大型灌区安全现状的基础上,重点论述了大型灌区工程风险源识别、安全评价、加固改造等方面的研究现状,并对大型灌区工程安全管理模式的发展趋势和若干关键问题进行了归纳总结,认为今后应在灌区风险识别和控制技术、服役条件下建筑物混凝土损伤演化、风险管控机制以及智慧化和数字化管理等方面深入研究,确保大型灌区安全长效运行,实现大型灌区现代化运行和管理。 |

Abstract: |
Large-scale irrigation area projects have long water transmission lines, huge number of various hydraulic structures, and some backbone projects 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, intelligent and digital management, etc, so as to ensure the safe and long-term operation of large-scale irrigation area projects and realize the modern operation and management of large-scale irrigation area projects. |
