10月22日至25日，中國鐵路工程總公司所屬中鐵二院承擔的新建鐵路云桂線初步設計順利通過專家評審。
云(yun)桂線(xian)(xian)(xian)(xian)(xian)(xian)(xian)正線(xian)(xian)(xian)(xian)(xian)(xian)(xian)及(ji)各(ge)類疏解(jie)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)共計897km，是(shi)在艱(jian)險山區修建的(de)一條長(chang)(chang)大干線(xian)(xian)(xian)(xian)(xian)(xian)(xian)，整個線(xian)(xian)(xian)(xian)(xian)(xian)(xian)路(lu)溝梁相(xiang)間，橋隧相(xiang)連，全線(xian)(xian)(xian)(xian)(xian)(xian)(xian)共有(you)橋梁259座，隧道186座，占線(xian)(xian)(xian)(xian)(xian)(xian)(xian)路(lu)總長(chang)(chang)的(de)71%。共設車(che)站20座，線(xian)(xian)(xian)(xian)(xian)(xian)(xian)路(lu)高程(cheng)由(you)78米(mi)的(de)南寧(ning)上升至1892米(mi)的(de)昆明，其中因線(xian)(xian)(xian)(xian)(xian)(xian)(xian)路(lu)跨(kua)越(yue)江河，還(huan)有(you)5次比較(jiao)大的(de)起伏(fu)，普者(zhe)黑至昆明段在188公里(li)范圍內跨(kua)（穿(chuan)）越(yue)“一湖兩江三盆(pen)五道梁”。線(xian)(xian)(xian)(xian)(xian)(xian)(xian)路(lu)還(huan)將(jiang)通過膨脹(zhang)土(tu)(tu)（巖）、巖溶(rong)、軟土(tu)(tu)、泥(ni)石流、滑坡多發區和八度地震(zhen)區，素有(you)“地質百科全書”之(zhi)稱，其工程(cheng)難度與(yu)南昆線(xian)(xian)(xian)(xian)(xian)(xian)(xian)不相(xiang)上下。
