摘要：本次毕业设计对青岛港董家口港区重力式码头进行了设计。董家口港区地基承载力优良，因而选择了耐久性好并且施工工艺简单、对荷载及工艺变化适应性较强的方块码头。本次设计主要对该码头的结构尺寸、荷载及其稳定性验算进行了设计与计算。

在对于码头的结构尺寸的选择上结合了多个实际方块码头设计案例与《重力式码头设计与施工规范》（JTS167-2-2009）等规范对码头断面进行设计。在码头作用分类与计算中，主要考虑了码头自重、波浪力、土压力、地震惯性力与船舶荷载，在土压力中又考虑了墙后棱体的永久作用、码头面堆存荷载的可变作用以及偶然作用地震时的墙后棱体与堆存荷载的土压力。荷载部分的选用取值主要参考了《港口工程荷载规范》（JTS144-1-2010）以及《水运工程抗震设计规范》（JTS146-2012）。最后运用设计规范对码头进行稳定性验算、地基沉降以及对卸荷板进行了配筋计算。

Abstract

The graduation design of the Qingdao Port Dongjiakou port gravity terminal was designed. Dongjiakou port area bearing capacity is excellent, and thus choose a good durability and simple construction process, the load and process changes adapt to the strong square pier. The design of the design of the terminal size, load and stability of the calculation and design and calculation.

The design of the pier section is combined with a number of practical block terminal design cases and the design of the Gravity Dock Design and Construction Specification (JTS167-2-2009) for the selection of the structural dimensions of the wharf. In the classification and calculation of dock function, the main consideration of the terminal weight,  wave  force,  earth  pressure,  seismic  inertial  force  and  ship  load,  in  the earth pressure and taking into account the permanent role of the posterior wall of the wall, the dock surface stacking load variable The role of the earthquake and the occasional action of the wall after the wall and the load load of the earth pressure. The selection of the load part is mainly based on the "Port Engineering Load Specification" (JTS 144-1-2010) and the  Code  for  Seismic  Design  of  Waterworks  (JTS  146-2012).  Finally,  the     design specification is used to calculate the stability of the pier,  the  foundation settlement and the reinforcement calculation of the unloading plate.

Keywords: design of the pier section; load calculation; stability checking
