建設成果

技術難題

銅陵公(gong)鐵長(chang)江大橋主橋工程難(nan)(nan)點在于：1、3號墩沉(chen)(chen)井(jing)基(ji)礎施(shi)(shi)工水文地質條件(jian)復雜，下沉(chen)(chen)過程中(zhong)(zhong)，遇到(dao)了事先未曾勘(kan)探(tan)到(dao)的(de)卵石膠(jiao)結層，使沉(chen)(chen)井(jing)下沉(chen)(chen)困難(nan)(nan)；2、中(zhong)(zhong)國國內首次(ci)采用雙(shuang)節間全(quan)焊(han)桁片組拼鋼桁梁(liang)結構，由于全(quan)焊(han)桁片制(zhi)造精度(du)要求高，因此桁片豎立存放運輸安(an)(an)全(quan)風險大，現場安(an)(an)裝(zhuang)工藝復雜；3、橋塔根(gen)部弦桿受力(li)(li)最(zui)大的(de)區(qu)段及邊墩和(he)輔(fu)助墩區(qu)域均采用正交(jiao)異性鋼箱橋面結構；鋼箱橋面板剛度(du)大，安(an)(an)裝(zhuang)時適(shi)應變形能力(li)(li)差(cha)，增加了安(an)(an)裝(zhuang)難(nan)(nan)度(du)；4、中(zhong)(zhong)國國內首次(ci)在鐵路橋梁(liang)上采用鋼絞線斜拉索，對施(shi)(shi)工中(zhong)(zhong)和(he)成(cheng)橋后(hou)每束斜拉索中(zhong)(zhong)單根(gen)鋼絞線之間的(de)索力(li)(li)誤差(cha)提(ti)出了很高的(de)控制(zhi)要求。
