摘要
黄河口拦门沙淤积发育变化对河口河段的发展演变有着显著的影响,拦门沙是造成河口河段泄水泄沙不畅、淤积加快、水位抬高和流路摆动的主要因素,特别是拦门沙发育到后期,门槛效应更加明显。拦门沙治理是黄河河口治理的重要组成部分,挖河疏浚作为黄河综合治理的一项措施,正日益受到重视。根据黄河疏浚的历史及近期工程实践经验,通过对黄河口拦门沙疏浚技术措施进行分析比较,提出具体对策技术措施。
Sediment transport and deposition has obvious effects on the development evolution of the Yellow River estuary.The sediment bar in estuary cause sedimentation growing at a faster rate,that is the main reason why the flow moving and the flow velocity is sluggish.The harness of sediment bar is one important part of the Yellow River estuary improvement.River dredging as a comprehensive management measures draws increasing attention from the society.The paper mainly analyzes the development and evolution of sediment bar,taking comparison for sediment bar dredging technology and measures according to Yellow River dredging practice,and the countermeasures are presented.
