摘 要

根据当地水文、地质、泥沙和集疏运等条件，完成了对苏州港5万吨级通用件杂码头工程的设计。设计包括了整个码头的总平面布置、装卸工艺的设计、码头结构的选型、方案的比选和结构的设计与校核。

该码头设计泊位为1个，设计船型为5万吨件杂货船。设计拟定了全直桩码头和有叉桩码头两种方案。通过码头方案的比选，对不同种桩台的稳定性和经济性进行了比较。选定了前方桩台两对叉桩的高桩梁板式码头的设计方案，码头共设有四个标准结构段。

在结构计算和构建模型时对结构型式及桩身受力进行了合理的简化，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。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，采用五弯矩方程matlab编程计算。验算了桩的极限承载力。

关键词：高桩码头；梁板式；总平面设计；结构方案

Abstract

According to the local hydrological, geological, sediment and collection and transportation conditions, the design of 50,000-ton general-purpose miscellaneous Wharf in Suzhou Port has been completed in this paper. The design includes the general layout of the wharf, the design of loading and unloading process, the selection of wharf structure, the comparison of schemes and the design and verification of the structure.

The wharf is designed with one berth and the design which is 50,000 tons of grocery vessels. Two schemes of full-straight pile wharf and fork pile wharf are designed and drawn up. Through the comparison and selection of wharf schemes, the stability and economy of different pile caps are compared. The design scheme of the high-piled beam-slab wharf with two pairs of cross-piles in front of the pile abutment is selected. There are four standard structural sections.

In the process of structural calculation and model building, reasonable simplification is made for the structure type and the force acting on the pile body, and the stress and reinforcement calculation of typical members (panel, cross beam, longitudinal beam, berthing member) is carried out. The wharf panel is a composite plate, which is calculated according to one-way plate. In this design, the longitudinal beam is considered as a rigidly supported

continuous beam, and the influence line method is used to calculate the longitudinal beam; the cross beam is considered as an elastically supported continuous beam, and the calculation is carried out by MATLAB programming according to the equation of five bending moments. At the end of the calculation,I get my ultimate bearing capacity of pile foundation and figured out the length of elastic pile are checked, and the calculation results are in line with the design requirements. Finally, the calculation results of reinforcement are drawn according to the drawing standards.

KEY WORDS: high-piled wharf; beam-slab type; general plane design; structural scheme
