天平铁路六盘山特长隧道施工关键技术的研究

Research on key technical to LiuPanShan specialty scales railway tunnel construction

针对天平铁路六盘山特长隧道的特点为单线特长隧道,工作面独头掘进段落长,工序干扰大,施工通风困难,工期紧张,为全线控制性工程之一;同时,隧道穿越中等富水区及弱富水区,涌水量大,且长距离反坡排水,施工排水难度大等工程特点。为实现2012年2月29日新建天平铁路六盘山隧道工程全面完工的建设总体目标,杜绝生产安全重特大事故和铁路交通重特大事故,减少较大和一般安全事故的安全目标,工程竣工后符合国家和铁道部有关标准、规范及设计文件要求,工程一次验收合格率100%,主体工程质量零缺陷的质量目标,结合现场施工特点,制定了相关的施工技术放案,确保了六盘山特长隧道顺利施工。

LiuPanShan specialty scales railway tunnel for single line tunnel, working face blind heading paragraph long pro cess,interference,construction difficult ventilation,tense in time limit for a project,control project for all one;at the same time,tunnel through the medium of water-rich area and weak water rich area,large flow of water over long distances, and the reverse slope drainage, construction drainage such as the difficulty of Engineering characteristics. To achieve the February 29,2012,new LiuPanShan specialty scales railway tunnel fully completed the construction of the overall goal,put an end to production safety accidents and railway traffic accidents,reduce large and general safety accident safety goals,after the completion of the project in line with my country and the Ministry of Railways relevant standards,specifications and design documents,engineering a qualified acceptance rate of 100% the main part of the project,the quality of zero defect quality goals,combined with the characteristics of construction .site,the construction technology put case,to ensure that the six mountain long tunnel construction.
