基本介紹

艾溪(xi)湖大橋位于中國江(jiang)西(xi)省南昌(chang)(chang)市(shi)，西(xi)起北京東(dong)(dong)(dong)路，主線以(yi)高架橋型(xing)式由西(xi)往(wang)東(dong)(dong)(dong)跨過艾溪(xi)湖南路、艾溪(xi)湖和昌(chang)(chang)東(dong)(dong)(dong)大道，接艾溪(xi)湖南路交叉(cha)(cha)口和昌(chang)(chang)東(dong)(dong)(dong)大道交叉(cha)(cha)口簡易立交，東(dong)(dong)(dong)至紫(zi)陽(yang)大道是南昌(chang)(chang)市(shi)東(dong)(dong)(dong)部的主出入(ru)口。

建筑設計

建筑結構

整體布局

艾溪湖大橋分別由(you)水(shui)上主橋、南(nan)北兩道引(yin)橋、拱(gong)肋(lei)、橋墩(dun)其立(li)交匝道組成(cheng)，主橋路段(duan)呈正(zheng)(zheng)西至正(zheng)(zheng)東方(fang)向布(bu)置。

設計理念

艾溪湖大橋采用外(wai)傾式拱橋作為方案，以(yi)對(dui)(dui)稱傾斜拱結(jie)構與橋外(wai)伸出(chu)的半圓人(ren)行道等相對(dui)(dui)，寓意(yi)“張開雙臂、擁(yong)抱(bao)藍天”，也象征南昌(chang)市(shi)美好的未來與日同輝(hui)。
