淤地坝防洪预警系统研究与设计

Research and Implementation of Early Warning System for Check-dams

黄河流域生态保护和高质量发展作为国家重大发展战略,受到了广泛关注。淤地坝作为黄土高原地区重要水土保持工程措施,在控制沟道侵蚀、拦蓄泥沙方面发挥了十分重要的作用。然而运行多年后,多数淤地坝已出现泥沙沉积大、坝体老化等问题,一旦水文气象条件发生变化,将严重影响坝系和流域安全。为了解决淤地坝管理信息化水平低、防洪预警机制不健全的问题,通过实地调研现有研究成果,在比较分析和专家研讨的基础上应用层次分析、RUSLE等方法,提出一种针对内蒙古黄河流域淤地坝的简化预警模型,设计了一套可实现淤地坝管理信息和预警信息可视化的防洪预警系统。根据真实数据进行实验验证了模型的可行性,为淤地坝工程安全度汛提供了技术保障,可全面提升淤地坝管理的信息化水平。

The ecological protection and high-quality development of the Yellow River Basin have received widespread attention as a major national development strategy.As an important soil and water conservation engineering measure in the Loess Plateau region,warping check-dams have played a very important role in controlling channel erosion and retaining sediment.However,after many years of operation,most silt check-dams have encountered problems such as large sediment deposition and aging of the dam body.Once the hydrological and meteoro⁃logical conditions change,it will seriously affect the safety of the dam system and watershed.In order to solve the problems of low informatiza⁃tion level of warping check-dam management and imperfect flood control early warning mechanism,a simplified early warning model for warp⁃ing dam in the Yellow River basin of Inner Mongolia was proposed based on comparative analysis and expert discussion,and a flood control early warning system that can realize visualization of warping dam management information and early warning Information visualization was de⁃signed.The feasibility of the model was verified through experiments based on real data,providing technical support for the safe flood control of the silt check-dam project and comprehensively improving the informationization level of silt check-dam management.
