摘要
CRD工法已经应用于玉蒙铁路黑龙潭隧道施工中。针对浅埋、软弱、偏压、膨胀岩等地质条件,本文对原设计CRD工法进行改进,采取有效的施工措施,完成大断面隧道的施工任务。
The CRD method has been applied to the construction of the Heilongtan tunnel of the Yumeng Railway.Aiming at geological conditions such as shallow burial,weak,biased pressure,and expansive rock,this paper improved the original design CRD construction method and adopted effective construction measures to complete the construction of large-section tunnels.
