摘要
利用2010—2012年两年4季莱州三山岛黄金海岸沙滩综合勘测结果,分析上述沙滩形成过程,并进行了沙滩近期变化特征探讨。结果表明,莱州三山岛黄金海岸沙滩年际及年内季节性变化规律均表现出带状冲刷特征,黄金海岸沙滩及其近海海域表现为普遍冲刷特征,冲刷厚度平均<1.2m/a。基于莱州三山岛黄金海岸沙滩近期变化特征,建议尽早开展以抛沙养滩为主,并适当辅以硬工程的沙滩养护方案,注重海滩养护工程前期调查,修复和人工再造三阶段的工作,特别应根据设计方案向沙滩开展大量抛沙、保沙和稳沙工作,使受蚀海滩逐步恢复。
According to the comprehensive observation results of Laizhou-Sanshandao beach from 2010 to 2012,the Scour and Silting Characteristics of short-term evolution are analyzed and the beach nourishment proposal is put forword.It is showed that the annual and seasonal variation characteristic of Laizhou Sanshandao is zonal scouring,and the beach and its offshore show general scour characteristics.The average erosion thickness is less than 1.2m/a.Based on the Laizhou-Sanshandao changes,it emphasizes on the beach nourishment firstly,and then hard engineering.Especially,it includes the three-stage of preliminary survey,reconstruction and repair.The beach is supplemented by throwing sand to restore gradually.
