印度尼西亞當地時(shi)間2月18日(ri)，由(you)中國中鐵(tie)(tie)(tie)旗(qi)下中鐵(tie)(tie)(tie)三(san)局(ju)參建的(de)雅(ya)萬(wan)高(gao)鐵(tie)(tie)(tie)全線最長隧(sui)道——6號(hao)隧(sui)道順利貫通。至此，中鐵(tie)(tie)(tie)三(san)局(ju)所承建的(de)雅(ya)萬(wan)高(gao)鐵(tie)(tie)(tie)8座(zuo)隧(sui)道全部實現貫通，標志(zhi)著施工(gong)生產取得重大階段性成果。

雅萬高(gao)鐵(tie)6號隧(sui)道(dao)全長(chang)4478米，是(shi)雅萬高(gao)鐵(tie)全線(xian)最(zui)長(chang)的單洞雙線(xian)山(shan)(shan)嶺隧(sui)道(dao)，隧(sui)道(dao)洞身下(xia)穿(chuan)河流、沖溝、村莊，最(zui)大埋深約96.9米。隧(sui)道(dao)地質復雜，主要為火(huo)山(shan)(shan)堆(dui)積層黏土、粉(fen)質黏土、泥(ni)(ni)巖(yan)、砂巖(yan)、火(huo)山(shan)(shan)角礫巖(yan)，易出現塌(ta)方、大變形、突(tu)水涌泥(ni)(ni)，安全風險(xian)高(gao)，施工(gong)難度大，是(shi)雅萬高(gao)鐵(tie)全線(xian)重點控制性工(gong)程。

自隧(sui)道(dao)(dao)開(kai)工(gong)(gong)(gong)建(jian)設(she)以(yi)來，中鐵(tie)三局全體建(jian)設(she)員工(gong)(gong)(gong)以(yi)高(gao)度的(de)使命感(gan)和責任(ren)感(gan)，堅守海外(wai)陣(zhen)地(di)，忠誠履職擔(dan)當(dang)，克(ke)服了(le)(le)當(dang)地(di)地(di)理氣(qi)候環境(jing)造成的(de)水土不(bu)(bu)服、語言(yan)溝通障礙、文(wen)化(hua)習俗(su)差異、物流(liu)運輸不(bu)(bu)便(bian)等(deng)不(bu)(bu)利影響，堅持(chi)疫(yi)情防控和工(gong)(gong)(gong)程建(jian)設(she)兩手抓、兩不(bu)(bu)誤，確保了(le)(le)工(gong)(gong)(gong)程建(jian)設(she)平(ping)穩(wen)有序(xu)推進。針對復雜地(di)質(zhi)(zhi)環境(jing)，中鐵(tie)三局項目(mu)部提出“巖(yan)變我變”的(de)施工(gong)(gong)(gong)策略，大(da)力(li)實施隧(sui)道(dao)(dao)機械化(hua)施工(gong)(gong)(gong)，對隧(sui)道(dao)(dao)開(kai)挖(wa)施工(gong)(gong)(gong)方案再細化(hua)再優化(hua)，分別采用“三臺(tai)階法”“三臺(tai)階臨時(shi)仰拱法”“CRD法”“三臺(tai)階七部開(kai)挖(wa)法”等(deng)隧(sui)道(dao)(dao)工(gong)(gong)(gong)法，對部分涌(yong)水段落采用洞(dong)身超前大(da)管(guan)棚、中管(guan)棚、徑(jing)向注漿(jiang)等(deng)措施，安全順(shun)利地(di)穿(chuan)越(yue)了(le)(le)復雜地(di)質(zhi)(zhi)環境(jing)。
