基于补偿水头差的沿江口门引排流量计算方法研究OA北大核心CSTPCD
Calculation method of diversion and drainage discharge through entrances of tributaries to Changjiang River based on compensated water head difference
长江支流口门多建有节制闸,利用涨落潮过程自行引排水,而引排水流态的复杂性使得引排流量过程难以精准确定.以太湖流域杨林塘口门为例,通过分析引排水调度方式及流态特征,发现涨潮时开启中孔闸门引水,内河侧流态复杂且附近水位差别大,而落潮时开启全部闸门排水,外江侧流态复杂且附近水位有所差别.为此,提出了一种基于补偿水头差的沿江口门引排流量计算方法.该方法通过设置系列补偿水头差修正堰流公式中的水位,统计了计算流量与实测流量偏差值,进而建立了流量偏差值与补偿水…查看全部>>
There are many control gates at the entrances of tributaries to the Changjiang River,which use the process of flood and ebb tide to divert and drain water by themselves.However,the complexity flow pattern makes it difficult to accurately deter-mine the process of diversion and drainage.Taking the Yanglintang estuary in the Taihu Lake Basin as an example,by analyzing the diversion and drainage scheduling methods and flow characteristics,we find that when the …查看全部>>
