摘　　要：为保障40万吨级矿石船安全进出曹妃甸港,通过ADCIRC潮位数学模型研究渤海潮波传播规律。结合船舶航行方式,采用多站联合法求取40万吨级矿石船在渤海超长深水航路的乘潮水位。结果表明:40万吨级矿石船在乘潮保证率90%、乘潮时间8h进入渤海水域的乘潮水位为1.0m,乘潮保证率90%、乘潮时间8h驶出渤海水域的乘潮水位为0.2m。可见同一乘潮保证率和时间下的乘潮水位,进入渤海水域明显高于驶出渤海水域;多站联合法确定的进入渤海水域乘潮水位大于单潮站确定的乘潮水位(0.6m);驶出渤海水域乘潮水位小于单潮站确定的乘潮水位(0.7m)。To ensure safety of the 400 000 DWT carrier during entering and leaving Caofeidian port,the propagation law of tidal waves in the Bohai Sea was studied by using ADCIRC tidal level mathematical model.Combining ship's navigation mode,the tide level of 400 000 DWT carrier in the Bohai sea super-long deep water route was calculated by means of multi-station joint calculation method.The results show that the tidal level of 400 000 DWT carriers is 1.0 m when it enters the harbor under the condition of 90% guarantee rate and 8 h tide ride,and the tidal level is 0.2 m when it departures under the condition of 90% guarantee rate and 8 h tide ride.Under the same tide ride duration and cumulative frequency,the tide level for entering Bohai sea is obviously higher than that for outbound.The tidal water level calculated by multi-station joint method is higher than that calculated by single tidal station method.Meanwhile,the outbound tidal level is less than the level calculated by single tidal station method.
