大风期黄骅港外航道的骤淤估算及防淤减淤措施探讨

Estimation of Sudden Sedimentation in Outer Channel of Huanghua Port During Rough Climate and Measures for Reduction of Sedimentation

黄骅港运用后,偏北大风引起外航道的泥沙淤积严重。根据2002年及2003年的实测数据,本文使用新近完善的风、浪、流共同作用下的输沙公式及已编制成的大风期航道回淤预报程序,进行回淤的验证和计算,计算表明:预报结果与实测比较相当符合。参考已有的文献资料,提出了用潜堤作为防淤减淤的措施。

There appeared serious sedimentation in outer channel of Huanghua Port during heavy wind climate after its operation. This paper presents a calculation and verification of sudden sedimentation by using the sediment transport formulas under coexistence of wind, waves and tidal currents, which was perfected recently, and the program compiled for waterway sedimentation prediction during heavy wind period named 'BEDMUD'. The calculation results are very close to those measured in outer channel during rough climate in 2002 and 2003. Taking the existing documents and information as a reference, this paper puts forward measures for preventing and reducing sedimentation by using submerged dikes.
