大独山隧道崩塌变形分析

摘要

Taking the Dadushan tunnel as the engineering background,this paper made site investigation to local collapse off block situation of line D1K859+902. 6 mileage section left and right sides haunches,according to the research results at home and abroad,from the terrain environment, geological structure,geological structure,artificial excavation,climatic conditions and other factors,analyzed the process of Dadushan tunnel gener-ating of compression shear collapse deformation,put forward corresponding processing suggestions,ensure the tunnel construction quality.%以大独山隧道为工程背景，对线路D1K859+902.6里程处左右两侧拱腰处发生局部崩塌掉块的情况进行了现场调查，根据国内外的研究成果，从地形环境、地层结构、地质构造、人工开挖、气候条件等因素着手，分析了大独山隧道产生压剪崩塌变形的作用过程，并提出了相应的处理建议，以确保隧道的施工质量。
