摘要
在介绍长江中游戴家洲河段航道整治总体工程和一期工程方案的基础上,重点分析一期工程的整治效果。一期工程整治效果主要体现在:稳定了戴家洲水道枯水期分流条件,直水道进口段弯道形态得到改善,弯道凹岸边界得以延长,弯道水流特性变强,进口段河宽受到控制,浅区航道条件改善,为总体工程的全面实施创造了有利条件并奠定了良好基础。
Based on the introduction of the regulation master plan and the first phase project plan of the Daijiazhou section,effects of the first phase project are analyzed.Their effects are mainly as follows： stabilizing the flow-diversion of Daijiazhou waterway during dry seasons;improveing the bend shape in the entrance of straight waterway;extending the concave length of the bend;strengthening the flow characteristics of the bend;controling the entrance width of Straight waterway;improving the channel conditions in entrance shallow area;creating favorable conditions and laying a solid foundation for the realization of regulation master plan.
