摘　　要：介绍兰渝铁路木寨岭隧道斜井施工期间高地应力软岩地段的大变形情况,并对变形情况结合地质条件、支护结构的合理性、工艺控制等因素以及监测数据进行分析,通过现场施工实际及理论分析提出有效、合理的支护措施;同时,指出下阶段高地应力软岩施工技术研究方向,为下步施工提供指导,也为类似工程提供借鉴。The large deformation occurring during the construction of the inclined shafts of Muzhailing tunnel on Lanzhou-Chongqing railway located in soft ground with high ground stress is presented. Analysis is made on the large deformation on basis of the geological conditions, reinforcement structures, construction process and monitoring data. Effective and reasonable reinforcement measures are proposed in accordance with the site conditions and the theoretical analysis. The technical trend for the subsequent construction of the tunnel in soft ground is provided. The paper can be served as guidance for the subsequent construction of the tunnel and as reference for similar projects in the future.
