摘 要

赤湾港区位于深圳港的西部港区，位于珠江入海口的东岸前缘，地理条件优越，距离深圳市区仅25公里。深圳港赤湾港区周边有群山环绕，珠江口岸外有浅滩密布，为赤湾港区提供了理想的天然屏障。港口内水深良好，港内水域开阔，各项配套设施完善，适合多种大型货物运输船舶的停靠和转运，是我国珠三角地带推动经济发展的综合多式联运码头。

赤湾港区8#泊位集装箱码头工程主要停靠船型为6万吨级PANAN AX型基桩集装箱船和5万吨级的散货船。本文涉设计拟定了全直桩高桩码头和有叉桩与斜桩支承的高桩梁板码头共两种方案。从码头的施工期与使用期两个阶段以及码头钢筋混凝土工程量的综合对比，最终选定本码头的设计结构为全直桩高桩梁板式码头。

本码头将横梁与纵梁设计为等高连接的形式，面板使用叠合板，依据工程地基的地质情况，采用全直桩的结构形式，将基桩打入地基的持力土层，充分使用基桩的抗弯能力。码头排架间距为10米，每榀排架为五跨梁，提高了码头的稳定性和承载力。

本码头面板结构使用单向板结构，面板支撑在纵梁上，纵梁搭载在横梁上，纵梁为刚性支承连续梁，横梁为弹性支撑连续梁，本码头使用影响线法对梁板结构进行计算。

设计完成了码头断面图、立面图和平面图的设计，完成了码头梁板安装图的设计，完成了码头面板配筋图与轨道梁配筋图的设计。

Abstract

Chiwan port area is located in the western port district of shenzhen port. It is located in the eastern front of the pearl river estuary. Shenzhen port chiwan port area is surrounded by mountains, and the pearl river port is dotted with shoals of shoals, providing an ideal natural barrier for chiwan port area. Good depth of water in port, port waters is open, perfect supporting facilities, suitable for a variety of large cargo ships docked and transport, is the pearl river delta area to promote the economic development of our country's comprehensive intermodal terminal.

The no. 8 berth container terminal project in chiwan port area mainly calls at the 60,000 ton PANAN AX type pile container ship and 50,000 ton bulk cargo ship. In this paper, a total of two schemes are proposed for the design of full straight pile high pile wharf and high pile beam and slab wharf with fork pile and inclined pile. From the two stages of the construction and use of the wharf and the comprehensive comparison of the amount of reinforced concrete in the wharf, the design structure of the wharf was finally selected as the slab wharf with full straight pile and high pile.

This dock will beam and girder design for the form of contour connection, panel using composite plate, on the basis of the geological condition of engineering foundation, adopts the straight pile structure form, the soil will pile into the foundation strength, fully use the pile bending capacity. The distance between the wharfs is 10 meters, and each truss is five beams, which improves the stability and bearing capacity of the wharf.

The dock panel structure using one-way slab structure, panel support on longitudinal beam, the longitudinal beam carrying on beams, longitudinal beam of rigid support continuous beam, beam and elastic support continuous beam, the terminal use of beam slab structure influence line method to calculate.

The design completed the design of the wharf sectional drawing, elevation drawing and planar drawing, completed the design of the wharf beam plate installation drawing, and completed the design of the wharf panel reinforcement drawing and track beam reinforcement drawing.

KEY WORDS: chiwan port area; Beam and plate piled wharf; The structure design
