“xaxwaswaswasxilxilx免费”西延高铁阳湾一xaxwaswaswasxilxilx免费号隧道顺利贯通

  中新xaxwaswaswasxilxilx免费网西安12月19日电 xaxwaswaswasxilxilx免费(记者 梅镱泷 张远)记者19日从中国铁路西安局集团有限公司获悉,由西成客专陕西公司建设、中铁三局集团有限公司承建的西延高铁阳湾一号隧道顺利贯通,标志着西延高铁全线又一座隧道施工取得重大进展,为后续无砟轨道的施工奠定了坚实的基础。

  据了解,西延高铁阳湾一号隧道位于陕西省铜川市宜君县,全长1812米,地貌属黄土残塬区,区内地形较起伏,地势北高南低,冲沟发育。隧道洞口坡面植被较发育,洞身上部城镇、道路密集,地貌受人为影响较大以及隧道最大埋深55米且穿越土石分界面和土体含水率较高,临近210国道,围岩大变形及坍塌风xaxwaswaswasxilxilx免费险较高。

  为确保隧道施工安全,西成客专陕西公司严格控制隧道施工进尺,浅埋段采用三台阶临时仰拱,有效控制沉降,保证施工安全。采用机械配合人工开挖,喷射砼及时封闭开挖面,利用超前小导管支护、钢拱支撑、挂网等加强围岩自稳能力,同时定期开展隧道施工安全质量隐患排查工作,并对隧道洞内及地表监控量测、掌子面围岩状况进行实时监测、反馈。施工中,项目部通过实施安全穿透式管理,强化跟班作业,规范班前讲话,过程安全盯控,科学优化施工组织方案,有效解决了湿陷性黄土地基承载力低、易变形等难题,确保隧道顺利贯通。

  西安至延安高速铁路是陕北革命老区的首条高铁,是国家高速铁路网包(银)海高速铁路通道的重要组成部分,与正在建设的西渝高铁共同形成南北大通道,是陕西省“米”字型高铁网主骨架的重要构成,是“十四五”时期的重点建设项目。线路全长299.8公里,建设标准为双线高速铁路,设计速度350公里每小时。

  据悉,线路建成投入运营后,西安至延安的运行时间将从目前的2小时30分钟缩短至1小时左右,对深入推进西部大开发战略、助力革命老区乡村振兴、加快构建包海高速铁路通道,进一步完善优化国家高速铁路网络布局、提升陕西省区位优势和全国铁路网枢纽地位具有重要意义。(完)
