粉沙质海岸的工程泥沙问题
Sediment Problems of Harbors on Silty Beaches
【摘要】 粉沙质海岸泥沙活跃,易起易沉,易发生骤淤,曾一度被视为建港"禁区",并成为泥沙研究的"盲区"。文中对粉沙质海岸建港中的工程泥沙问题进行了分析总结。
【Abstract】 The sand on the slity beach moves actively.The threshold velocity is slow and the settling velocity is fast,and the rapid siltation often occurs.Few harbors have been built on this kind of beaches and so,it’s lack of research on it.In this paper,analysis and summing-up of sediment problems on the beaches is made.
