在岩石地基或较坚硬的地基上建造码头,一般多采用沉箱、混凝土方块等重力式结构.如在港内水域狭小或防护差的地方建造直立式岸壁码头,往往会恶化泊稳条件.在这种情况下,可以采用装配式排架透空式码头结构.它既可改善泊稳条件,又可缩短工期降低工程造价.装配式排架码头结构由以下几部份组成:下部结构,由带基墩的大型钢筋混凝土排架构成;上部结构,由钢筋混凝土无梁板或粱板构成.本文对这种码头结构型式的设计及施工特点,作了简单扼要的介绍.
The construction of piers on rock foundations or harder foundations generally uses gravity-type structures such as caissons and concrete blocks, etc. Upright wharf piers, where there are narrow or poorly protected areas in the harbor, tend to deteriorate the mooring conditions. In the case, it is possible to adopt an assembly-type pierced pier structure which can improve the condition of parking stability and shorten the construction period, thereby reducing the construction cost. The structure of the pier with pierced structure is composed of the following components: The upper structure is composed of reinforced concrete beamless plate or beam board.This paper briefly introduces the design and construction characteristics of this type of wharf structure.
