摘要
基于对秦皇岛洋河口附近海域海底439件表层沉积物、40件柱状样进行粒度分析,了解洋河口附近海域表层沉积物以及砂层分布情况,确定调查区内西南侧浅表层沉积物主要以细砂、中细砂为主,可作为海滩养护砂源;东北侧以粘土质砂和砂·粉砂·粘土为主,不适合直接用于海滩养护工程。
Based on the analysis on the grain size of 439 surface sediments and 40 columnar sed-iments near the Yanghekou, Qinhuangdao, the distribution of surface sediments and sand layers near Yanghekou were concluded, and it was found that the surface sediments in the southwest of the investigation area were mainly composed of fine sand and medium sand, which can be used as beach nourishment, the surface sediments in the northeastern are mainly composed of the sandy soil and sand-silt sand- clay, not suitable for direct beach nourishment.
