阳江核电厂取水构筑物泥沙回淤特征研究
Study on the surface sediment and siltation characteristics of water intake structures of Yangjiang Nuclear Power Plant
摘要
Abstract
Based on particle size and bathymetry measurements of sediments in the water intake structure of the Yangjiang Nuclear Power Plant,the sediment sources and characteristics were studied,and the siltation mechanism was discussed.The results show that the sediment in the water intake structure enters with the water intake dynamic force from the harbor mouth,and the suspended sediment settles to the seabed where the flow velocity decreases.The siltation rate is low in the main flow path and high at the edges and corners of the harbor basin and wave dissipation pond,and at the end of the channel.Based on bathymetry surveys,the sedimentation rate in the water intake structure of the Yangjiang Nuclear Power Plant is about 0.22 m/a.Furthermore,due to the influence of typhoon waves,a large amount of suspended sediment is stirred up and transported into the water intake structure,resulting in rapid siltation and the formation of a mud layer that persists for more than ten days.关键词
