摘要
河道上的人工采砂活动改变了原有的河床演变规律,对工程河段通航等功能的发挥产生一定影响。为了探究采砂活动对河床演变的影响,本文结合具体工程实例,在该采砂活动前后勘测河段河床地形,并结合近年来地形资料,对该采砂工程对河道河床演变的影响进行后评估研究,为类似工程提供参考。
Artificial sand mining activities on watercourse changes original riverbed evolution law with certain influence on navigation in engineering river section and other functions. In the paper, concrete engineering example is combined, and river section riverbed terrain is investigated before and after sand mining activities. The ten＇ain data in recent years are combined for post-assessment study on the influence of the sand mining project on watercourse riverbed evolution, thereby providing reference for similar projects.
