摘　　要：通过不同时期的水深对比对龙口湾拦江沙坝的稳定性进行研究,从其形成过程和现代泥沙运动的角度对拦江沙坝冲淤变化的机制进行探讨。研究表明,该沙坝范围和轮廓稳定,但坝体泥沙在波浪作用下发生沿坝输移和横向输移,在人工开口情况下有较为明显的冲淤响应。In this paper, the erosional and depositional stability of the Lanjiang sand bar in the Longkou Bay is studied by making a comparison between water depth data in different periods, and the erosion and deposition mechanisms of the Lanjiang sand bar are discussed by analyzing the formation process of sand bar and the sediment movement around sand bar. It is shown from the study results that the scope and outline of sand bar were stable, but the sediments on the bar were transported along and across the bar under the actions oi waves, and obvious erosion and deposition variations of sand bar occurred after the sand bar having been artificially opened.
