摘要
以郑西铁路客运专线函谷关隧道各工作面贯通施工为例,总结出CRD、弧形导坑等不同开挖方法间的贯通要点,指出该工法符合大断面黄土隧道施工安全、快速的要求,特别当黄土隧道断面大于160 m2时更为有效。
Taking the breakthrough construction of each working face of Hanguguan Tunnel of the passenger special line on Zhengzhou-Xi＇ an Railway as the example, this paper sums up the main points of the breakthrough among different excavation methods such as CRD, and parenthetic pilot tunnel, etc., and points out that this method, which is in accordance with the requirements of the safe and rapid construction of the loess tunnel with large section, is more effective when the section of the tunnel is larger than 160 m2.
