1概述

1.1工程概況

鳳凰三橋跨越下橫瀝水道，兩岸地勢平坦，江面寬約420m,水深約5?10

m,橋下船舶通行繁忙，_1.游北岸離橋邊線190m處設有三千噸級碼頭，南岸離

橋邊線110m處設有千噸級散貨碼頭。主橋通航孔按I級航道標準，通航凈高

Hm=18m、凈寬Bm=200m,最高通航設計水位采用二十年一遇洪水位7.46m。

考慮水下地形、水深、上游兩岸碼頭以及橋墩寬度與防撞等因素，設單個雙向通

航孔時，跨徑取308m,并將主跨布置在河流中央。

主橋跨徑組合為40+61+308+61+40m=510m,邊中跨比0.198,主橋長為

510m,大致成對稱布置在河道中，并以61m跨到達河堤邊。以40m跨越南岸

河堤。主跨為中承式系桿斜拉鋼混組合拱橋，邊跨主梁為碎結(jié)構，中跨主梁為鋼

校組合結(jié)構，吊桿縱向間距為10.2m。橋面以上拱肋為鋼箱結(jié)構，橋面以下三角

剛架為混凝土結(jié)構。主拱采用矢跨比為1/4.5,拱軸系數(shù)為m=1.25的懸鏈線箱

形拱肋。拱肋向內(nèi)以1：5的斜率傾斜，構成提籃式拱。

1.3主要材料

主體結(jié)構采用Q345qC；

部分含有Z向受力的采用Q345qE-Z25;

附屬結(jié)構采用Q235B；

組合結(jié)構中混凝土采用C50鋼纖維混凝土。

1.4荷載組合

設計中考慮了三種荷載組合:

荷載容許應力

所包含荷載工況

組合增大系數(shù)

組合1成橋恒載十汽車十人群1

組合2成橋恒載+汽車+人群+溫度+風力251.25

組合3成橋恒載+溫度+風力皿1.25

成橋恒載指包括自重、沉降在內(nèi)的永久作用。

其中風力25是根據(jù)《公路橋梁抗風設計規(guī)范》（JTG/TD60-01-2004）中的

相關規(guī)定，在風荷載參與汽車荷載組合時，橋面高度處的風速Vz取為25m/s。

風力3L3是取廣州地區(qū)重現(xiàn)期為100年的基本風速值31.3m/So

1.5容許應力

根據(jù)《公路橋涵鋼結(jié)構及木結(jié)構設計規(guī)范》（JTJ025-86）的有關規(guī)定，在

不同荷載組合下容許應力可以相應有不同的提高。

組合一200210120

組合二250262.5150

組合三250262.5150

同時參考《日本道路橋示方書》中的規(guī)定，鋼材的容許應力需要考慮荷載組

合、整體穩(wěn)定、局部穩(wěn)定和板厚的影響：

Qca=OcagXOcal/Ocac

式中（Jca為容許軸向壓應力

第4頁

鳳凰三橋鋼拱肋及組合梁結(jié)構計算15

Ocag為考慮整體穩(wěn)定但未考慮局部穩(wěn)定的容許軸向壓應力

CJcal為考慮局部穩(wěn)定的容許彎曲應力

Qca。為未考慮穩(wěn)定的容許軸向壓應力

得到Q345鋼材的容許應力，見下表：
