摘　　要：水东湾建港自然条件良好,唯拦门沙顶水深很小,能否开挖航道是建港的关键问题。多年来未能决策建港。经过研究和计算分析,认为拦门沙航道开通后、流速增加,回淤量不大,可以开发。1992年,拦门沙航道开挖成功,并建成3万t级油码头一座。航道回淤量及拦门沙滩顶上流速增加值与预报值基本相符。The natural condition for harbour extension in the shuidong bay is good but depths at the crest of mouth bar are very shallow, hence the maintenance of the mouth bar channel is a key problem for the larger harbour construction. The decision to extend the harbour has not made for years. Through study and analysis and numerical modelling, it is known that the sedimentation amount in outer channel of the bay is not much and the current velocities especially during ebb period increase after completion of the dredging of mouth bar channel, i, e, the dredging of the mouth bar channel is feasible, In 1992, the channel of mouth bar was successfully dredged and a berth of 30000 tonnage grade was constructed. The sedimentation amount in navigation channel and the current velocities increasing at the crest of the mouth bar are a good agreement with those in prediction.
