Preliminary analysis on basic characteristics and mechanism of rockfalls in layered red rocks with gentle dip angle: A case study of the Tiejiangwan rockfall in Hongya County, Sichuan province

  • 摘要: 红层区常发育缓倾角岩质边坡,因其软硬相间的岩性组合,地质灾害频发、灾害严重。基于光学卫星遥感、无人机航空摄影测量、现场调查等天空地一体化的技术手段,以2021年4月5日发生的四川洪雅铁匠湾缓倾角红层岩质崩塌为研究对象,探讨了崩塌的基本特征和成因机理,分析了铁匠湾陡崖区崩塌灾害发展趋势,以期为红层区类似灾害的研究提供资料支撑。结果表明,铁匠湾崩塌可分为主崩塌区和崩塌影响区两个区域,其中主崩塌区包括崩源区1处、铲刮区1处、堆积区1处、流水二次搬运堆积区1处,崩塌影响区包括潜在崩源区1处、扰动变形区5处。崩塌源区具有“上硬下软”的岩石组合,岩体发育两组近于垂直的优势结构面,2013年已表现出变形迹象,在降雨、温差的持续作用下导致了源区危岩体的最终失稳垮塌,巨大的冲击力作用于危岩体下方的老崩塌堆积体和基岩,引起崩塌-碎屑流灾害链。在光学遥感影像解译和野外调查的基础上,认为铁匠湾崩塌存在二次崩塌的风险,在崩塌邻区识别出类似崩塌隐患点6处,建议采用无人机、机载LiDAR等技术手段开展铁匠湾陡崖区崩塌隐患的早期识别与持续监测。
