淤泥质海岸人工沙滩的维护问题日益为人们所关注。在平衡水深概念推导出的海床冲淤公式的基础上，通过对平衡流速的假设，增加了因水深改变而引起的海床冲淤，推广了适用于计算自然滩面下海床冲淤的公式。通过推广后的公式计算了连云新城海滩清淤工程的泥沙冲淤。计算结果表明：各清淤方案有使海床恢复到自然水深的趋势，且均有泥滩出露的现象，需要进行定期的疏浚维护。

The maintenance of artificial beach in silt coast has been increasingly concerned. Based on the formula of sea bed erosion and siltation derived by the concept of equilibrium depth, through the assumption of equilibrium velocity, the sea bed scouring and silting caused by the change of water depth is added. The formula which is adapted to the calculation of erosion and siltation of natural seabed is generalized. The sediment scouring and silting of the beach dredging project in the new city of Lianyungang is calculated by the new formula. The result shows that the seabed tend to reduce to original depth after every dredging project is implemented. Mud is exposed and regular dredging maintenance is needed.
