新港防波堤系1942年日本侵华期间建造的。由于该地区堤前水深较浅,堤基较差,砂石料来源缺乏,且水上施工及设备条件也有限,因此所采用的结构型式多为混合式(即我国《海港水文》规范中的基床域高基床直立堤)。由于该防波堤的设计和施工限于当时条件,比 Newport Breakwater was built in 1942 during Japan’s invasion of China. Due to the shallow water depth in front of the embankment in the area, the poor dike foundation, the lack of sources of sand and gravel, and the limited water conditions for the construction and equipment, most of the structural types used are hybrid (ie, the foundation bed in China’s “Harbor Hydrology” Field high bed upright embankment). Due to the design and construction of the breakwater is limited to the conditions at that time
