建筑設計

建筑結構

整體布局

艾(ai)溪湖大橋(qiao)(qiao)分別由水(shui)上主(zhu)橋(qiao)(qiao)、南(nan)北兩道(dao)引(yin)橋(qiao)(qiao)、拱肋、橋(qiao)(qiao)墩(dun)其立交匝道(dao)組(zu)成，主(zhu)橋(qiao)(qiao)路段(duan)呈(cheng)正(zheng)(zheng)西(xi)至正(zheng)(zheng)東方向布置。

設計理念

艾(ai)溪湖(hu)大橋采用外傾式(shi)拱橋作為方(fang)案(an)，以對稱(cheng)傾斜拱結構與(yu)橋外伸出的(de)(de)半圓(yuan)人行(xing)道等相對，寓意“張(zhang)開(kai)雙臂、擁抱藍天”，也象征南昌(chang)市美好的(de)(de)未(wei)來與(yu)日同(tong)輝。
