摘要
以黔张常铁路隧道工程通过水平岩层为研究对象,通过介绍其围岩失稳的特点,对处于水平岩层围岩中的隧道施工中发生的掉块坍塌原因及针对性施工措施进行归纳和分析,为今后同类围岩状况隧道的修建提供参考。
Based on Qian Zhang Chang railway tunnel engineering by horizontal rock formations as the research object,the level of surrounding rock in tunnel construction of metal shed collapsed,summarized the cause and the corresponding construction measures and analysis,provide a reference for similar conditions of surrounding rock tunnel construction in the future.
