12月(yue)10日(ri)，中鐵二局(ju)施(shi)工(gong)(gong)的(de)龍廈鐵路控制性工(gong)(gong)程上(shang)東(dong)(dong)山(shan)隧(sui)道(dao)中部至出口段提前19天順利(li)貫通(tong)。上(shang)東(dong)(dong)山(shan)隧(sui)道(dao)總長4657米(mi)，其中中部至出口段長2555米(mi)。上(shang)東(dong)(dong)山(shan)隧(sui)道(dao)屬(shu)山(shan)區地(di)(di)(di)(di)貌，地(di)(di)(di)(di)質(zhi)構造(zao)極(ji)為復雜，洞身穿過巖性分界接觸斷(duan)裂帶、地(di)(di)(di)(di)下水發育帶、淺(qian)埋(mai)軟(ruan)弱帶等不良(liang)地(di)(di)(di)(di)質(zhi)帶，施(shi)工(gong)(gong)難度很大。項目部針對復雜地(di)(di)(di)(di)質(zhi)條件，不斷(duan)優(you)化施(shi)工(gong)(gong)設(she)計，嚴格現場施(shi)工(gong)(gong)管理，對特殊地(di)(di)(di)(di)段及時調整施(shi)工(gong)(gong)方案，時刻抓好施(shi)工(gong)(gong)過程中的(de)安全(quan)質(zhi)量工(gong)(gong)作，確保了工(gong)(gong)程順利(li)提前貫通(tong)。
