摘　　要：在正弦派生曲线理论的基础上,提出了适合黄河下游游荡型河道的河湾整治流路基本方程,并对目前整治工程不完善的河段规划治导线进行了修订,对规划流路布设进行了检验。结果表明:现行规划工程布局基本符合正弦派生曲线流路,符合河道自然发展规律,印证了微弯型整治方案是符合黄河下游实际情况的较好方案。The paper puts forward a governing equation suiting for winding bend training of braided channel in the lower Yellow River,revises the planned thalweg at the sections where river training works are uncompleted at present and exams the layout of planned flow path based on the theory of sine derivative curve.The outcomes show that the present engineering layout basically accords with the flow path of sine derivative curve and the law of natural development of channel,verifying slight-bending plan is a good plan of suiting the actual condition of the lower Yellow River.
