“37西方大但人文艺术任汾”成达万高铁华蓥山37西方大但人文艺术任汾隧道贯通

  12月237西方大但人文艺术任汾3日,随着华蓥山隧道最后37西方大但人文艺术任汾一次爆破完成,新建成都至达州至万州高速铁路(以下简称“成达万高铁”)全线高风险、重难点控制性工程——华蓥山隧道顺利贯通。

  华蓥山山岭陡窄,峰峦层叠,地形地貌环境极为复杂。成达万高铁华蓥山隧道长8735米,为单洞双线、高风险瓦斯隧道。隧道掘进过程中,面临煤层采空区、突泥涌水、岩溶富水、软土浅埋等多种不良地质,建设难度系数很大。

  成达万高铁西起成都市天府站,终至既有郑渝高铁万州北站,全线设13座车站,其中遂宁站、南充北站、万州北站3座车站为既有车站,天府站等10座车站为新建车站,建设工期5年。

  成达万高铁是中国“八纵八横”高铁网沿江通道的重要组成部分,正线长477公里,设计时速350公里。(记者 刘忠俊 视频制作 岳子岩)
