本文概述了以往对连云港外航道的回淤研究,提出了连云港外航道以悬沙落淤为主的回淤计算方法。计算结果与现场试验挖槽及其他资料的比较验证,表明计算结果是符合实际的。在验证计算的基础上,对连云港扩建的外航道回淤作出了预报。从外航道的可能回淤情况来看,连云港可以发展成为深水大港,那种认为外航道经几次大风就会淤塞的论点,似缺科学根据。
This paper summarizes the previous studies on siltation in the outer channel of Lianyungang, and proposes a silt-calculating method for silting mainly sediment deposition in the outer channel of Lianyungang. Comparing the calculation results with the field test trench and other data, it shows that the calculation result is in line with the actual situation. Based on the verification and calculation, the siltation of the outer channel of Lianyungang expansion was predicted. Lianyungang may develop into a deepwater port from the possible siltation of the outer waterway. The argument that the outer waterway will be blocked by several gale forces seems to lack scientific basis.
