建筑設計

建筑結構

整體布局

艾溪湖大橋(qiao)(qiao)分別由水上(shang)主(zhu)橋(qiao)(qiao)、南(nan)北兩(liang)道引橋(qiao)(qiao)、拱肋、橋(qiao)(qiao)墩其立(li)交匝道組成，主(zhu)橋(qiao)(qiao)路段呈正西至正東方向布置。

設計理念

艾(ai)溪湖(hu)大橋采用外傾(qing)(qing)式(shi)拱(gong)橋作為方案，以對(dui)稱傾(qing)(qing)斜拱(gong)結(jie)構與橋外伸出的半圓人行道等相對(dui)，寓意“張開雙臂、擁抱藍(lan)天(tian)”，也象征南昌市美好的未來與日(ri)同輝。
