| 中文摘要 | 贵州关岭2010-06-28特大滑坡(简称"6.28"特大滑坡)造成99人死亡,其形成受到当地气候条件、地质条件和地貌等因素影响,发生机制和滑动具有一定的独特性。通过对滑坡的形成条件、发育特点和成因分析,揭示了此次滑坡的形成特征。研究表明:降雨是此次滑坡的诱发因素;滑坡具有分块滑动的特点,即坡积层和基岩先后发生滑坡;滑坡堆积体具有明显的"二元结构"特征,即滑坡堆积体前缘以及中下部为碎石土堆积,而上部为碎块石堆积,与一般滑坡堆积不同,是坡积层与基岩先后发生分块滑动的典型证据。研究成果对认识和研究此类滑坡具有重要的科学意义,也可为今后指导防灾和减灾提供参考。 |
| 英文摘要 | Landslide killed 99 persons in Guanling County ,Guizhou on 28th of June, 2010. It was influenced by local climatic conditions, geological conditions and topography conditions, and its formation mechanism and slippage were unique. The paper revealed the formation mechanism of this landslide through analyzing the formation conditions, developed characteristics and formation mechanism. Analysis showed that the landslide was triggered by rainfall, and the movement of landslide was partitioning that the bedrock glided after eboulis ordonnes sliding. In addition, landslide accumulation had the dual structure feature that landslide in the lower and the front part was gravel soil and block stone, while the landslide in the upper part of the accumulation was block stone. This structure was different with the accumulation of general landslide characteristics, and it was a typical evidence of twice landslides. The result was important for studying similar type of landslide and provided a reference for disaster prevention and disaster reduction in future. |
