| 摘 要： | 本文根据大亚湾大鹏澳菱角石沿岸的波浪、潮流和泥沙资料,探讨了菱角石沿岸泥沙来源、泥沙活动水深和破波带,估算了破波带沿岸输沙率和非破波带底沙单宽输沙率,说明了沿岸泥沙运移以破波带沿岸输沙为主,验证了赵子丹提出的估算沿岸输沙率的关系曲线的可靠性。

| Abstract: | Based on the information of wave, tide and sand of Lingjiaoshi in Dapengao sea area, Daya Bay, the thesis inquires into the problems concerned with the source of sand, water depth of active sand and the breaker zone.It calculates the littoral transport rate in the breaker zone and the per-width sand transport in the non-breaker zone. The results show that sand transport in the breaker zone is the prirrary factor in littoral drift. At the same time, the results also testify the reliability of curve counting littoral transport rate as proposed by Zhao Zidan. |
