【摘要】 黄河河口拦门沙是河海动力相互作用后径流势能锐减,咸淡水混合,泥沙絮凝加速沉积而成的堆积体,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重要因素。通过对以往黄河口口门5种疏浚技术方案的综合分析比选,推荐绞吸式挖泥船和扰沙船两种技术方式相结合进行疏浚黄河口拦门沙。更多还原

【Abstract】 the sandbar in Yellow River estuary is the deposit body of silt and sand,which is formed due to reduction of runoff potential energy and mixing of fresh and salty water after the interaction between sea and river dynamic force.It is the main factor that causes unsmooth of water and silt discharging,increase of silt deposition,rising of water level and course swaying.After comprehensive analysis and comparison between five dredging schemes used in Yellow River estuary in the past,the dredging method of combination of cutter suction dredge and sand disturbing dredge is recommended on sandbar dredging in Yellow River estuary.更多还原
