摘要
为提升碧江区瓦屋河流域山洪灾害预警能力,实现对该流域内某典型区域降雨量的全覆盖监测。文章基于信息熵理论优化雨量站布设优先级,结合流域地形特征,在河流交汇处、山洪易发区等关键位置布设6个雨量站,实现降雨量实时监测。同步设计导流设备安装方案,通过围堰施工与基坑排水设备配置,完成自适应导流系统建设。实例验证表明:导流量偏差≤5 m^(3)/s,站点覆盖密度达35 km^(2)/站,监测数据采集频率为5 min/次,区域山洪灾害防控效能得到显著提升。
To enhance the early warning capacity of mountain flood disasters in the Wawu River Basin of Bijiang District and achieve full coverage monitoring of rainfall in a certain area within the basin,this study optimizes the priority of rainfall station deployment based on the information entropy theory.Combined with the topographic features of the basin,6 rainfall stations are deployed at key locations,such as the confluence of rivers and areas prone to mountain floods,to achieve real-time monitoring of rainfall.The installation plan for the diversion equipment is designed simultaneously.Through the construction of the cofferdam and the configuration of the foundation pit drainage equipment,the construction of the adaptive diversion system is completed.The case verification shows that the deviation of the guiding flow is no more than 5 m^(3)/s,the coverage density of the station reaches 35 km^(2) for each station,the frequency of monitoring data collection is 5 minutes per time,and the effectiveness of regional mountain flood disaster prevention and control has been significantly improved.
