摘　　要：大试件单轴蠕变实验表明，板岩流动变形破坏受结构面控制。即使在同一方向应力作用下，也表现了平行走向、反倾向、顺倾向方向的差异。这是板岩流动变形破坏各向异性的另一种表现形式。Large samples uniaxial compressive creep test indicates, the flow deformation and failure of slate is controlled by its structure plane. Although under the same directions stress,it also whows the differences among the parallel strike direction,reverse strike direction and trend direction. This is another appearence of slate flow deformation and failures anisotropy.
