摘要本工程拟建 30000 吨级重力式沉箱码头，位于广州南沙港区。靠船构件及码头附属设施等都是按照 30000 吨级散货码头设计施工。 本码头的设计计算内容内容主要有：码头泊位尺度的计算及泊位的设计包括泊位数78310

目的计算；通过按规范计算确定码头的结构布置及型式选择；结合实际对码头总体平面 进行布置；按确定的沉箱码头结构型式对其进行结构设计以及确定码头附属设施；按照 地质条件和荷载情况对码头的稳定性是否符合要求进行计算；通过作用在结构上的荷载 计算出结构的内力以方便配筋；根据算好的结构内力对需要配筋的结构进行配筋计算； 根据实际工程情况对施工过程进行施工组织设计。

根据算好的码头设计内容确定本码头适宜重力式沉箱码头的结构型式。该码头型式 的结构计算内容主要包含：根据工程实际对沉箱的尺寸进行确定；按照确定的沉箱尺寸 再对其在各种水位情况下的自重力进行准确的计算；计算三种水位情况下沉箱受到的土 压力，静水压力以及波浪力；根据吨位确定该码头面上的堆货荷载，仓库储存荷载和与 码头吨位相适应的船舶作用在码头上的荷载。

根据结构计算内容对码头整体进行验算，内容包含：整个码头结构是否符合稳定性 要求的码头整体稳定性验算，对沉箱结构的面板，隔板以及地板的配筋进行验算；最后 当稳定性和配筋验算都符合要求后对沉箱进行抗裂验算。

Abstract The project proposed 30,000-ton Gravity Caisson Wharf, located in Guangzhou Nansha Port。 Berthing member and marina ancillary facilities are in accordance with the design and construction of 30,000-ton bulk cargo terminal。

Design Pier computing content content: calculated berths scale and berth design includes berth calculation of the number; by pressing the norms calculated structural arrangement determine Pier and Type Selection; actually on the pier overall plane arranged binding; according to the determined caisson wharf structure type determines its structural design and marina ancillary facilities; according to the geological conditions and loading conditions on the stability of the pier to meet the requirements calculated; by acting on the structure of the load calculation of the internal forces to facilitate the reinforcement structure; according to Internal Forces need quite good reinforcement structure reinforcement calculation; according to the actual situation of the construction process engineering construction design。

According to design content is quite good Wharf Pier determine appropriate gravity caisson wharf structure type。 Structural calculations contents of the pier type mainly includes: The actual dimensions of the caisson is determined according to the project; then accurately calculate its level in a variety of situations from gravity caisson determined in  accordance with size; Calculate three water level under the caisson by the earth pressure, hydrostatic pressure, and wave power; determined according to the tonnage of the cargo  pier pile surface load, warehouse storage and ship loading dock tonnage of the role and adapt load on the pier。

According to the structure of the pier whole calculation content checking, contains: The entire marina dock structure meets the requirements of the overall stability of checking the stability of the panel, partitions and floor reinforcement caisson structure were checking; and finally when stability with after checking the ribs meet the requirements of the caissons were crack resistance。

Keywords: caisson wharf；load calculation；checking overall；
