| 英文摘要 | Abstract The Brazil disk test is carried out for thin layered rock with different thickness by numerical simulation method, with the load and AE data of samples analyzed.The following are some findings: (1) When the thickness of a single layer of layered rock increases, its tensile strength does not simply increase. Instead, they roughly show a U-shaped relationship. (2) Layered rock’s load-displacement curve is multimodal. (3) Shear rupture occurs at the upper and lower ends of the disk, tensil and mixed rupture occurs more frequently in the middle of the disk. (4) There are three stages of of interacting cracks’ coalescence: initial crack and the secondary fracture generate, then they interact and extend, lastly coalesce. |
