【摘要】：建立了淮河中游洪河口至浮山段一、二维耦合水动力数学模型,采用实测洪水过程对模型进行验证,验证结果表明,模型具有较高的精度。基于水动力数学模型,在现状工况条件下,对1954年型洪水进行了调度模拟分析,研究了临淮岗洪水控制工程、行蓄洪区与分洪河道等防洪工程联合调度运用效果。计算结果表明,对于1954年型洪水,淮河干流行蓄洪区全部启用,不启用临淮岗工程,蚌埠以上大部分河段水位超保证水位,蚌埠以下河段水位低于保证水位。启用临淮岗工程,可以减轻下游的防洪压力,减少行洪区启用数量,减少行蓄洪区淹没面积,同时也增加了上游蓄洪区和部分河段的淹没水深和高水位历时。综合全河段分析,启用临淮岗工程,干流大部分河段水位较低,行蓄洪区淹没面积减少,防洪效果较优。
[Abstract]:The coupled hydrodynamic mathematical model of the first and second dimensional coupling between the flood estuary and the Fushan in the middle reaches of the Huaihe River is established. The model is verified by the measured flood process. The verification results show that the model has a high accuracy. Based on the hydrodynamic mathematical model and under the condition of present working condition, the operation simulation analysis of 1954 flood was carried out, and the combined operation effect of flood control project, flood storage area and flood diversion channel in Linhuaigang was studied. The calculation results show that for the 1954 flood, the flood storage areas of the main stream of the Huaihe River are all open, but the Linhuaigang Project is not used. The water level of most of the reaches above Bengbu is above the guaranteed water level, and the water level below Bengbu is lower than the guaranteed water level. The application of Linhuaigang Project can lighten the flood control pressure, reduce the number of flood discharge areas, reduce the submerged area of flood storage area, and increase the submerged depth and duration of high water level in upstream flood storage area and part of river reach. According to the analysis of the whole river reach, Linhuaigang Project is put into use, the water level of most of the main stream reaches is low, the flood storage area is reduced, and the flood control effect is better.
