长江河道采砂的影响及其控制利用的试验分析

Experimental Analysis of the Impact of Sand Mining in the Yangtze River and its Control and Utilization

以长江芜湖铜陵马鞍山段为例,使用基于微尺度模型的模拟试验的方式,结合近景摄影测量三维图像解析技术的应用,针对河道采砂对河床变化情况产生的影响进行了试验分析,其结果为采砂作业的合理展开以及河床稳定性的维护提供了参考。

Taking the Tongling section of Wuhu in the Yangtze River as an example,using the simulation test method based on the micro-scale model,combined with the application of three-dimensional image analysis technology of close-up photogrammetry,the impact of river sand mining on the change of riverbed is tested and analyzed,and the results provide a reference for the rational development of sand mining operations and the maintenance of riverbed stability.
