| 摘 要： | 为了解分区破裂现象发生时内部裂纹的分布和沿巷道轴向的变化规律,以及这一现象容易在什么样的(岩石)材料中发生,利用4种不同的材料制作了模型,观测了钢桶模型内部裂纹的分布规律及沿轴向的变化规律。研究发现三个试验中出现了螺旋线,一个出现了"梯田"形的变形破坏特征。

| Abstract: | Four kinds of similar materials were used to establish four barrel models in order to find the crack distribution along the tunnel axial direction and the influence of material properties on the zonal disintegration phenomenon.It was found that spiral line appeared in three tests and one appeared terrace-shaped deformational and failure. |
