| 摘 要： | 采用控制体积法与SIMPLE算法对一般曲线坐标系下的水流控制方程进行离散求解，建立了一般曲线坐标系平面二维水流数学模型。并用来对大岗山水电站下游弃渣场与永久大桥工程建设后遭遇百年一遇洪水时的防洪影响进行了数值模拟。结果表明：工程修建后最大壅水高度为0.91m，位置在桥前200m。流速最大增加值为4.3m/s，出现在桥下游130m处。 |
| 关 键 词： | 一般曲线坐标 二维水流数学模型 防洪 弃渣场 大桥 |

| Abstract: | A model in generalized curvilinear coordinate is presented to simulate 2--D horizontal flow. Current governing equations are discretized by control volume method and SIMPLE algorithm. The paper has done the analysis and calculation of the water flow movement in the lower reach of Dagangshan hydraulic as well as the influence of the project of Yongjiu bridge and excavation waste dump on the flood--control . The results show the maximum height of the dammed water is about 0. 91 m at the length of 200m in front of the bridge and the maximum increase of water flow velocity is about 4. 3m/s at the length of 130m downriver. |
| Keywords: | generalized eurvilinear coordinate 2-- D horizontal flow flood-- control exeavation waste dump bridge |
