摘要
实地勘测嘉陵江礼嘉河段基础上提出采砂方案,采用贴体正交坐标系下的平面二维水流数学模型研究嘉陵江礼嘉边滩采砂后河道水流条件的变化。结果表明,采砂对河床演变、通航、河道行洪以及涉河工程的影响很小。
An excavation scheme on Lijia sediment bar of Jialing river was put forward based on site investigation, and a two-dimensional horizontal numerical model in orthogonal body-fitted coordinate for flow was established to study the variation of flow condition at Lijia reach caused by excavation. The results of calculation shows that the effect of excavation on riverbed evolution, navigation, flood carrying capacity and wading engineering of Jialing river is very small.
