摘　　要：从河势流路稳定性和河床稳定性等方面分析了黄河下游游荡型河道整治对河势的控制效果。结果表明:经采用微弯型整治方案后,游荡型河段的主溜平均摆动范围逐渐减小,河流稳定性明显提高;每处工程稳定靠溜长度不小于2300 m、工程长4 500 m左右,可以基本稳定游荡型河道的河势,但主流仍会在一定范围内变化。The paper analyzes the effects of river training conducted at meandering channel of the lower Yellow River from the aspects of the stability of river regime,channel bed and flow path.The outcomes show that a) the mean wandering range of the main flow reduces gradually and the stability of river increases remarkably after adopting a correction plan with slight-curves;b) when the length of main current stably come into contact with each engineering works is greater than 2 300 m and the length of project about 4 500 m,the river regime of meandering channel can basically stabilize,but the main flow still would change within a certain range.
