| 摘 要： | 以重庆市大渡口区大沙坝采砂区为例,采用二维水流数学模型对拟定的采砂区采砂后工程河段的水流条件进行模拟计算,就工程河段的航道条件及水域条件进行了分析。结果表明:按照设计的采砂方式和采砂工程量对该河段的航道基本不会带来负面影响。

| Abstract: | Taking the artificial sand-excavation engineering of Chongqing Dashaba in Yangtze River as an example,the flow conditions of the tentative sand-excavation region were analyzed by the 2D-model on water,with the emphasis focusing on the channel and water area condition of the sand excavation.The results show that following the designed sand-excavation approaches and quantities would have no obvious unfavorable influences on the channel. |
