摘要
通过对灌河口上游和外海来水来沙量及外航道历史演变的分析 ,表明新沂河泄洪对灌河口的河床有较大影响 ,上游各支流的下泄量较小 ,外海的来水来沙量主要与纳潮量和外海波浪对海底掀沙能力的大小有关。外航道整治方案回淤量计算结果为 :开挖万吨级航道泥沙回淤量为 2 2 0万 m3/ a,开挖 3.5万吨级航道回淤量为 32 0万 m3/ a。航道开通后 ,燕尾港可分期建设 8个万吨级泊位。
WT5”BZ]Through the analysis of flow, tide, sediment transport and topography variation in the Guan River Estuary, sone research results are obtained, showing that the flood from the Xinyi River and the tidal current and sediment from the sea affect the channel, and that the quantity of tide and sediment from the outer sea is relative to the volume of tide and the sediment transport capacity of waves. The silt calculation of the outer sea channel shows that after the training project, 2 200 000m 3 of sediment per year will be silted up if a 10 000t channel is built or 3 200 000m 3 of sediment per year will be silted up if a 35 000t channel is built. The training plan is quite feasible and 8 berths of 10 000t each in Yanwei Harbor can be constructed stage by stage in the future. [WT5HZ]
