| 摘 要： | 在改进王义刚等提出的淤泥质海岸围垦淤积计算方法基础上,提出了波流共同作用下围垦促淤计算方法。采用实测水沙资料对挟沙力公式进行率定,得到了横沙东滩水域波流共同作用下半潮平均水沙关系式,其相关系数明显优于仅考虑潮流作用的水沙关系式。采用上述计算方法和水沙关系式对横沙东滩促淤圈围工程的淤积效果进行计算,计算结果与实测值较为接近。由于考虑了波浪作用对含沙量的贡献,比仅考虑潮流作用的计算模式具有明显优势,以后可进一步尝试采用本模式研究砂质和粉砂质潮滩促淤效果问题。

| Abstract: | A new silting calculation method for the reclamation works under the wave and current interaction has been established by improving Wang Yi-gang′s calculation method applied to muddy coast shore reclamation. The coefficients of flood and ebb averaged sediment-carrying capability formula under the wave and current interaction are determined by the measured data of current velocity， wind speed and suspended sediment concentration， and the analysis results are significantly better than those which only consider the tidal flow. The siltation intensity of the eastern Hengsha shoal enclosure engineering has been calculated using the above method and the calibrated sediment-carrying capability formula， and the research results agree with the measured values. Because of considering the wave contribution to the sediment concentration， this model has obvious advantages over the calculation model only considering the tidal action. This model can be further tried to calculate the siltation intensity of the reclamation works placed in the silty and sandy tidal flat. |
