摘 要

本次毕业设计码头工程是对长江下游某化工公司的专用码头进行扩建，从而将使目前危险品码头泊位紧张拥挤状况得到彻底改善，可以降低船舶运输成本，提高码头装卸效率，增加可观的经济利益。平面布置根据《河港工程总体设计规范》（JTJ212-2006），确定了码头前沿高程为7.0m，码头长117m，宽10m。由于工程所在地处于长江中下游，受潮流影响水位差较大，结构型式采用了梁板式高桩码头。设计提出两种结构方案，最终结合技术经济性及发展空间选取了其中一种作为优选方案。在结构计算和构建模型时对结构型式进行了合理的简化，并对典型构件（面板、横梁、纵梁、靠船构件）进行受力和配筋计算。码头面板为迭合板，按单向板计算。本设计将纵梁按刚性支撑连续梁考虑，采用影响线法计算；横梁按弹性支撑连续梁考虑，按照五弯矩方程采用matlab编程计算。此外，在计算过程中对桩基极限承载力、弹性桩长度进行了验算，计算结果均符合设计要求。最后，对配筋计算结果按制图标准进行施工图的绘制。

Abstract

The graduation design wharf engineering is a chemical company in the Yangtze river downstream of wharf extension, which would make the dangerous goods berth congestion radically improve nervous, can reduce the shipping cost, improve the efficiency of port loading and unloading, increase the considerable economic benefits..The layout is based on《Overall design specifications of River port project》(JTJ212-2006) and combination of the DongShi Material Trade pier project downstream which is to be built. The terminal front elevation is 7.10m.The length of the berth is 117m while the width is 10m.As the project is located in the middle and lower reaches of the Yangtze River, the larger trend of the impact of water level difference, the structure of the type uses beam—slab type, high—pile pier.The design proposes two structures solutions and eventually selects one as the preferred solution by combination of technologies and economics as well as development space. A reasonable simplification is carried out in the structural calculations and building models of the structure, and the calculations of the force and reinforcement of typical components (panels, beam, longeron, berthing member). Terminal panels are laminated boards, calculated by way slabs.In the design,stringers are considered as rigid support continuous beams, calculated using the influence lines.Beams are considered as elastic support continuous beams using matlab programming in accordance with the five calculated moment equations. In addition, check computations of ultimate bearing capacity of pile foundations and the length of elastic piles are done in the process of calculation. Calculation results are in line with the requirements. Finally, building drawings are drawn in accordance with cartographic standards and the results reinforced construction.

Key words: Beam Piling Wharf；The rigid support continuous beam；The elastic supporting continuous beam.
