摘要：本次毕业设计的内容是烟台港区的油码头结构设计，对该码头进行方案对比，并对码头的沉箱部分进行结构内力的计算。根据码头的相关地质情况，再结合油码头的特点以及各种码头形式的优缺点，确定本次油码头采用重力式沉箱结构。在我的这次毕业设计中，首先初步确定了沉箱的外形尺寸，然后进行作用分析，按照永久作用、可变作用、偶然作用列出码头荷载的标准值，然后在此基础上进行稳定性验算。最后进行作用效应组合,并对沉箱前后面板和底板等进行配筋计算和抗裂验算。最后绘制图纸，包括码头平面图、三视图以及配筋图，本次设计的全部图纸全部采用AUTOCAD绘制。

Abstract：The design of the graduation project is Yantai port oil terminal structure design, the terminal for the program comparison, and the wharf part of the structure of the internal force calculation. According to the relevant geological conditions of the terminal, combined with the characteristics of the oil terminal and the advantages and disadvantages of various forms of the terminal,we determined the oil terminal using gravity caisson structure.

In my graduation design, the initial shape of the caisson was first determined, and then the action analysis was carried out. The standard values of the terminal load were listed according to the permanent effect, the variable effect and the accidental effect, and then the stability check was carried out on this basis.Finally, the effect combination, and the caisson before and after the panel and floor, such as reinforcement calculation and anti-cracking check.

Finally the drawings were drawed, including the terminal planing, all the drawings are used with AUTO CAD software.

Key words: gravity dock; caisson; oil wharf; floating stability
