摘要：为加快港城发展步伐，提高原材料的供应，于连云港赣榆区拟建一座沉箱式码头，主要营运的是铁矿石。连云港港主体为淤泥质海岸线，码头的结构形式多采用高桩梁板式结构，连云港港“一体两翼”的重要北翼——赣榆港区，是连云港港重要的拓展地带，是实现港城可持续发展的重要支撑，并且此处海域的地质条件很好，承载力较高，适合建造沉箱式码头，与此同时，沉箱式码头的沉箱结构水下工作量小，结构整体稳定性好，抗震性能强，施工速度较快。所以，决定在此建造沉箱式码头。

设计主要从平面布置与规划、沉箱尺寸确定、结构作用分类及计算、码头稳定性验算、沉箱内力计算等相关内容进行了相关设计。并最终进行承载力、结构稳定性、裂缝宽度等验算均符合规范规定。

关键词：沉箱结构，平面布置，内力计算，稳定性验算

Abstract：To speed up the pace of development of Lian Yungang and improve the supply of raw materials, a caisson wharf is proposed in Ganyu District of Lianyungang to transport iron ore.

The main body of Lianyungang harbor is muddy coastline,so that the structure form of wharf is mainly made of high piled beam slab structure. Ganyu port area is an important north wing of Lianyungang port and is an important expansion zone of Lianyungang port, the geological conditions are good with High bearing capacity that fit for caisson wharf.At the same time, the caisson structure of caisson wharf is small with good overall stability and strong seismic performance, construction speed is faster too. Therefore,we decide to build caisson wharf.

The design content mainly includes layout and planning, determination of caisson dimensions, classification and calculation of structure action, wharf stability checking and caisson internal force calculation.Finally,we pass the verification of bearing capacity, structural stability and crack width.

Key words: caisson structure , plane layout , calculation of internal force , stability checking
