摘要
在分析长江新济洲汊道段河床演变特点及发展趋势的基础上,通过模型试验对整治方案进行了研究,结合长江中下游分汊河道整治原则,认为长江新济洲汊道段的整治采用中汊封堵方案,虽然对新生洲、新济洲左右汊分流条件稍有影响,但有利于新济洲河段向稳定的双分汊河道发展.
Based on the analysis of the characteristics of fluvial process and the trend of development at Xinjizhou branched channel on Yangtze River,the regulation shcemes were studied through model tests. According to the regulation principles of branched channels in the middel and lower reaches of Yangtze River,the blockage scheme of middel channel at Xinjizhou branched channel were adopted. Although the scheme had certain impact on the diversion condition at left and right branches of Xinshengzhou and Xinjizhou,it would be helpful to the development of Xinjizhou branched channel towards the river with stable double branches.
