摘　　要：利用连云港地区的实测资料 ,对窦国仁输沙关系式进行了率定和修正 ,推导出新的潮流和波浪共同作用下的挟沙力关系式 ,进而建立了非恒定的平面二维不平衡冲淤计算数模并用实测和河工模型资料进行了验证。验证表明 ,计算结果符合实际。用经过验证的数模 ,对连云港核电站各种取、排水工程布置方案进行了冲淤计算 。Based on the field data, a formula to calculate sediment carrying capacity was firstly derived by calibrating and modifying the Dou's formula.A 2 D mathematical model on erosion and sedimentation was then developed to simulate the sediment transportation under the combination actions of tidal flow and wave. The model verified by field data and physical model results was used to optimize the arrangement of the water intake from sea and outlet to sea of the Lianyungang Nuclear Power Station. Satisfactory results were achieved.
