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)間無序多管(guan)交(jiao)匯(hui)桿系施工(gong)(gong)(gong)(gong)綜(zong)(zong)合(he)技(ji)術(shu)”應(ying)用“計算(suan)機仿真(zhen)模擬(ni)技(ji)術(shu)”并結合(he)“三維(wei)擬(ni)合(he)測量技(ji)術(shu)”，準確(que)確(que)定了構件(jian)吊裝(zhuang)(zhuang)和(he)卸載(zai)順(shun)序，解決(jue)了空(kong)間無序多管(guan)交(jiao)匯(hui)桿系鋼(gang)結構的(de)施工(gong)(gong)(gong)(gong)這(zhe)一(yi)行業性(xing)難題(ti)。“多塔大(da)跨度雙向疊(die)挑(tiao)鋼(gang)結構綜(zong)(zong)合(he)施工(gong)(gong)(gong)(gong)技(ji)術(shu)”對疊(die)挑(tiao)結構分(fen)級安裝(zhuang)(zhuang)和(he)卸載(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(ying)力過大(da)問題(ti)。其自主研制的(de)大(da)跨度連(lian)體桁架(jia)成套安裝(zhuang)(zhuang)施工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)藝，包(bao)括(kuo)多種支撐(cheng)形式及針(zhen)對性(xing)的(de)卸載(zai)方(fang)式等，對同類項目施工(gong)(gong)(gong)(gong)具(ju)有借(jie)鑒意義。
