  Large deformations occurred during the construction of tunnel in schist layer can be divided into 4 patterns,namely deformation controlled by rock property,deformation controlled by rock structure,deformation resulting from unsymmetrical load and deformation influenced by blasting.

  通过对大断裂区域片岩地层巷道工程中出现的大变形问题进行分析研究,将大变形类型划分为岩性决定型、结构决定型、地形偏压型和爆破扰动型。
