| 摘 要： | 利用平衡含沙量建立海床冲淤计算公式,由此导出海床冲淤指标新概念,得出海床冲淤判别式,用来预测海床冲淤演变趋势。进一步利用上海国际航运中心洋山港区全潮水文测验资料,计算出海床冲淤指标,预测该海区海床冲淤趋势,预测结果与现场实测很一致。

| Abstract: | A seabed siltation calculation formula is established by using the balanced sediment concentration,and thus a new concept of seabed erosion and siltation index is derived and a discriminant of seabed erosion or siltration is obtained to predict the evolution trend of seabed.The tidal hydro-geological test data for Yangshan Port area collected by Shanghai International Shipping Center is further used to calculate the seabed siltation indices and predict the seabed siltation trend.The predicted result is exac... |
