摘　　要：黄河下游滩岸易崩退,主流易摆动,尤以游荡段最为显著,危及防洪安全。当前定量模拟河势变化过程仍是河流动力学领域一大难题。从滩岸变形、深泓摆动等方面研究了小浪底水库运行后游荡段河势的变化特点,揭示了影响河势演变的主要因素,并提出了滩岸变形及深泓摆动的定量模拟技术,可为黄河下游河道治理提供科学依据。The bank of the lower Yellow River is prone to collapse and the main stream is prone to swing,especially the wandering section,which endangers the safety of flood control.At present,the quantitative simulation of the process of river regime change is still a difficult problem in the field of river dynamics.The characteristics of river regime change in the wandering section after the operation of Xiaolangdi Reservoir are studied from the aspects of bank deformation and the swing of the lowest point of the channel.The main factors affecting the evolution of river regime are revealed,and the quantitative simulation techniques of bank deformation and the swing of the deep lake are put forward.
