| 摘 要： | 利用平衡含沙量原理，通过水槽试验得出悬扬型和沉降型两种平衡含沙量及相应表达式，进一步利用平衡水深概念，导出海床冲淤计算公式，利用该公式计算了上海国际航运中心洋山港区的海床冲淤变化，计算结果与物理模型试验结果一致，验证了该公式的合理性，可以应用于实际工程中。

| Abstract: | Based on equilibrium silt concentration principle, expressions of raise equilibrium silt concentration and subsidence equilibrium silt concentration are obtained through the tank test, and a formula for seabed evolution calculation is derived from the equilibrium depth conception. The seabed evolution in Yangshan Harbor Area of Shanghai International Shipping Center is calculated by the formula, the result agrees well with the physical model test. The rationality of this formula was verified and can be applied in practical projects. |
