摘要
利用粒子追踪、中子活化示踪砂技术以及赵冲久和Yalin等相关公式对黄骅港抛泥区泥沙运移规律进行了研究,并在此基础上分析了抛泥区对黄骅港航道淤积的影响。结果表明,在正常天气下,抛泥区的泥沙运移主要受潮流控制;在大风条件下,泥沙运移则受到波浪、潮流、风生流等多种因素的影响;抛泥区泥沙几乎不会对航道淤积产生直接影响,其对航道淤积的影响是间接和有限的。
Particle tracking,neutron activation tracer sediment technique and formulas of Zhao and Yalin have been used to conduct research on sediment transport in mud-dumping grounds of Huanghua port.Furthermore,through these studies,effect on seaway siltation is analyzed.Results show that the sediment transport is dominated by tidal current under normal weather;nevertheless,under the condition of strong winds,wind wave,tidal current and wind-driven current play important roles in the sediment transport.Sediments fr...
