| 摘 要： | 通过采用河道平面二维水流数学模型对襄樊河段水流运动以及襄樊电厂二期工程大件码头及取水口工程对防洪的影响进行了数值模拟计算。结果表明：工程修建后上游河段最大壅水高度约0．02m，最大壅水长度约为630m，水流流态及水流流速分布无明显变化，对防洪影响不大。 |
| 关 键 词： | 河道平面二维 水流数学模型 防洪 码头 取水口 |

| Abstract: | Based on a depth-averaged 2 D numerical river model, the paper has done the analogue and calculation of numerical values in the water flow movement of the river sector of Xiangfan as well as the influence on the flood-control by Xiangfan power house enlargement project including Dajian port and intake construction. The results show the maximum height of the dammed water for the upper reach after the enlargement is about 0.08m with the length of 630m, and the water flowing state and the distribution of the water flow velocity of the river sector at the project site have no obvious change, so they have no greater influence on the flood-control. |
