基本介紹

艾(ai)溪湖(hu)大(da)橋位于中國江(jiang)西(xi)省南昌市，西(xi)起北京東(dong)(dong)路，主線以高架橋型式由西(xi)往東(dong)(dong)跨過艾(ai)溪湖(hu)南路、艾(ai)溪湖(hu)和(he)昌東(dong)(dong)大(da)道，接艾(ai)溪湖(hu)南路交叉口(kou)(kou)和(he)昌東(dong)(dong)大(da)道交叉口(kou)(kou)簡易立交，東(dong)(dong)至紫陽(yang)大(da)道是南昌市東(dong)(dong)部的主出入口(kou)(kou)。

建筑設計

建筑結構

整體布局

艾溪湖大(da)橋(qiao)(qiao)分別由水上主(zhu)橋(qiao)(qiao)、南北兩道引橋(qiao)(qiao)、拱肋(lei)、橋(qiao)(qiao)墩其立交匝道組成，主(zhu)橋(qiao)(qiao)路段(duan)呈正西至正東方向布置。

設計理念

艾溪湖大橋采用(yong)外傾式拱橋作為方案，以對(dui)(dui)稱傾斜拱結構(gou)與(yu)橋外伸出的半(ban)圓人行道等相對(dui)(dui)，寓意(yi)“張開(kai)雙(shuang)臂、擁抱藍天”，也象征南昌(chang)市美好的未來與(yu)日(ri)同輝。

建設成果

技術難題

艾(ai)溪湖大(da)橋在主(zhu)橋上采(cai)用了MIDAS2006程(cheng)序進(jin)行(xing)(xing)計(ji)算；結構(gou)為(wei)空間(jian)體系，該計(ji)算中(zhong)采(cai)用了三(san)維有(you)限元模(mo)(mo)型計(ji)算。由于鋼(gang)箱梁(liang)比較(jiao)寬，計(ji)算模(mo)(mo)型采(cai)用梁(liang)格法進(jin)行(xing)(xing)模(mo)(mo)擬(ni)(ni)；主(zhu)梁(liang)、主(zhu)拱采(cai)用空間(jian)梁(liang)單(dan)元模(mo)(mo)擬(ni)(ni)，斜拉索采(cai)用單(dan)元模(mo)(mo)擬(ni)(ni)。
