摘要
在分析莲沙容水道河势的基础上 ,对实施切嘴工程前、后火烧头分流区的河床形态、流场和泥沙冲淤分布 ,以及李家沙水道的分流比进行了物理模型试验 ,并建立了李家沙水道分流比与水面比降的关系式 .
On the basis of the river regime analysis of Liansharong Waterway, the river-bed variation , velocity , flow pattern, scouring and silting distribution in the reach and the diversion ratio of Lijiasha Waterway before and after the outcut work of Huoshaotou are studied. The relationship between the diversion ratio of Lijiasha Waterway and the water surface gradient is also presented.
