| 英文摘要 | Anchor often support layered rock mass with weak structural planes in engineering. In this research, combined with Digital Image Correlation technology (DIC), the impact tests of layered sandstone with different dip angles before and after anchorage were carried out at 7.5 m/s,8.5 m/s and 9.5 m/s. The results show that the anchorage effect can improve the strength of layered sandstone, and the dip angle is the most significant at 45 degrees. At the same time, the anchor can inhibit the germination and expansion of new cracks and reduce the fractal index of sample crushing. Finally, the effective conditions of the anchoring effect under impact load and the control mechanism of cracks are discussed. The research results can provide reference for anchoring support of layered rock mass. |
