前言重力式码头是港口工程中常见的一种码头结构型式,它一般在地基较好的情况下采用,但根据当地的施工条件,如地基较差仍需采用时,则地基经过妥善处理,也是可行的。重力式码头就其结构型式来看,最早的是干地施工的现浇混凝土墙(或)浆砌块石墙。随着施工水平的不断提高,发展到预制混凝土方块和砌石方块的水下安装,后来为了节省石料和劳动力,又出现了钢筋混凝土沉箱和钢筋混凝土块壁结构。而就混凝土方块来看又有无底空心方块和有底空心方块以及半空心半实心
Introduction Gravity wharf is a kind of wharf structure commonly used in port engineering. It is generally used in good foundation conditions. However, if the foundation construction still needs to be adopted according to the local construction conditions, the foundation is properly treated and feasible. Gravity quay on the structure of its type point of view, the first is the dry construction of cast-in-situ concrete wall (or) masonry stone wall. With the continuous improvement of the construction level, the underwater installation of prefabricated concrete blocks and masonry blocks has been developed. Later, in order to save stone materials and labor force, reinforced concrete caissons and reinforced concrete block wall structures have appeared. And on the concrete box there is no bottom hollow square and bottom hollow square and half-hollow half-solid
