近日，中國建筑工程總公司所屬中建鋼結構公司研發的“間無序多管交匯桿系施工綜合技術”和“多塔大跨度雙向疊挑鋼結構綜合施工技術”獲鑒定為國際先進水平，“帶單向斜拉桿的大跨度桁架鋼屋蓋關鍵施工技術”獲鑒定為國內領先水平。
“空(kong)間(jian)無(wu)序多(duo)管(guan)交匯桿(gan)系(xi)施工(gong)(gong)(gong)(gong)綜(zong)合技術”應用(yong)“計算機(ji)仿真(zhen)模擬(ni)(ni)技術”并結合“三(san)維擬(ni)(ni)合測量(liang)技術”，準確確定了構件吊裝(zhuang)和(he)卸載(zai)(zai)順序，解決了空(kong)間(jian)無(wu)序多(duo)管(guan)交匯桿(gan)系(xi)鋼結構的施工(gong)(gong)(gong)(gong)這(zhe)一行業(ye)性(xing)難題(ti)。“多(duo)塔大跨度雙向(xiang)疊挑鋼結構綜(zong)合施工(gong)(gong)(gong)(gong)技術”對(dui)疊挑結構分(fen)級安裝(zhuang)和(he)卸載(zai)(zai)，有效避免了施工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)程中變(bian)形不協調(diao)和(he)內應力過大問(wen)題(ti)。其自主研制的大跨度連體(ti)桁架成套安裝(zhuang)施工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)藝，包括多(duo)種支(zhi)撐形式及針對(dui)性(xing)的卸載(zai)(zai)方(fang)式等，對(dui)同類項目施工(gong)(gong)(gong)(gong)具(ju)有借(jie)鑒意(yi)義(yi)。
