摘要:
本文针对六盘水至沾益铁路三联隧道高地应力状态下凝灰岩软弱地层段出现的大变形问题，通过工程类比、数值理论分析后，采取了与之适应的施工工法、支护理念和设计参数，及时施做二次衬砌，较好地解决了极高地应力状态的软岩大变形问题，可为类似工程提供参考。
Abstract:
During the construction of three-connected-arch tunnel in Liupanshui-Zhanyi railway, the large deformation occurs under high ground stress in the soft tuff stratum section. In order to solve the deformation problem under extremely-high ground stress state, the appropriate construction method, support concept and design parameter are adopted after engineering analogy and numerical theory analysis and the secondary lining is performed in time, which can provide reference for similar projects.
