摘要
以长江大沙坝砂石采区后评估为例,着重研究项目实施后对该河段通航水流条件的影响。通过建立二维数学模型复演工程河段项目实施前后流场,数模计算结果显示采砂活动对该河段水位及流速影响较小,总体对通航影响较小,同时综合目前河道采砂现状,为采砂活动提出建议。
This paper takes the Dashaba sand mining area of the Yangtze River for an example, we focuse on the influence of river sand mining. on the navigable flow condition. A two-dimensional mathematical model illustrates the change of flow field after river sand mining. The results show that the sand mining activities have little effect on the river water level and velocity,and have a little effect to navigation. Combing current status of river sand mining, put forward some suggestions for the sand mining activities.
