摘要
基于大量的实测地形资料,分析近年来兴隆枢纽下游河段的河床演变特征,并探讨其主要影响因素.结果表明,研究河段的河床演变是上游来水来沙条件改变、水利枢纽建设及航道整治工程实施等共同作用的结果.在上游水沙条件变化不大、河段内整治建筑物整体稳定的前提下,整体河势将保持相对稳定.通过对研究河段平面形态、纵向冲淤及横向变化的分析,可更好地了解工程河段河床演变规律,为预测兴隆枢纽下游河段河床演变规律提供科学依据.
Abstract
Based on a large number of measured topographic data,this paper analyzes the characteristics of riverbed evolution in the lower reaches of Xinglong Hub in recent years,and explores the main influencing factors.The results indicate that the riverbed evolution of the studied river section is the result of the combined effects of changes in upstream inflow and sediment conditions,construction of water conservancy hubs and implementation of waterway regulation projects.Under the premise that the upstream water and sediment conditions do not change much and the regulation buildings in the reaches are stable,the overall river regime will remain relatively stable.By analyzing the plane shape,longitudinal erosion and sedimentation,and lateral changes of the studied river section,it is possible to better understand the evolution law of the riverbed in the engineering river section,and provide scientific basis for predicting the evolution law of the riverbed in the lower reaches of Xinglong Hub.
