【摘要】 对长江中游戴家洲河段的航道变迁及碍航特点进行了分析。依据河床演变分析,对分汊河段的择汊问题进行了探讨,对航道整治原则进行了深入思考,并确定整治原则为:维持分汊、择汊直港,守控洲头、调整水流、护岸守滩,综合布局、统筹兼顾。进而提出了3个航道整治基本思路,并根据航道整治目标河型的概念选择了目标河型。在河床演变分析及整治思路的基础上,提出了航道整治工程总平面布置设想。更多还原

【Abstract】 The characters of navigation-obstruction of Daijiazhou reach in Middle Yangtze River is analyzed.On the basis of the alluvial process analysis,the selection of navigable channel is discussed,and the channel regulation method is investigated,and the channel regulation principle is presented.The definition of target river pattern is put forth,and the target river pattern of Daijiazhou reach is selected.Based on the regulation method,the total channel regulation engineering is proposed.更多还原
