针对雅砻江锦屏二级水电站泄洪时,会对下游大河湾产生一定安全影响的问题,根据雅砻江大河湾地形地貌、历年实测水文数据以及锦屏二级泄洪方案,建立雅砻江大河湾防洪安全与决策支持系统,为水库泄洪安全及下游防洪决策提供技术支撑。该系统主要包括防洪安全信息维护和防洪安全与决策支持模型两大模块。从系统的建设目标、总体架构、开发设计及系统功能展示等方面进行了详细阐述。该系统通过各功能模块的交互工作,实现对泄洪区域防洪安全的辅助管理和决策支持,降低了下游河段的泄洪风险,确保了人民群众的生命财产安全。
According to Yalong River Jinping Ⅱ hydropower station discharge, it will have a certain safety impact on the downstream Dahewan, according to the Yalong River Tahe Bay topography, hydrological data over the years and Jinping two flood discharge program, the establishment of the Yahe River Bay flood control Safety and decision support system to provide technical support for flood discharge safety and downstream flood control decision-making. The system mainly includes flood prevention safety information maintenance and flood control security and decision support model two modules. From the system’s construction goals, the overall structure, development and design and system function display and other aspects were described in detail. The system through the interaction of the various functional modules to achieve flood control flood control safety and decision support, reducing the risk of flood discharge downstream, to ensure that people’s lives and property safety.
