关岭县北部岗乌永窝大寨6.28特大滑坡碎屑流灾害,造成99人死亡及失踪。通过调查类似地质条件下该地区地质灾害隐患分布情况。以该地区大田小学崩塌为代表分析该类型危岩带形成的原因及形成机理,分析了危岩体稳定性及发展趋势,并运用rockfail软件对滚石运动路径、影响范围、弹跳高度、运动能量做了分析。结合该地区自然条件,提出了相应的防治建议。对该地区类似崩塌(危岩)的防治,有一定的借鉴作用。
關嶺縣北部崗烏永窩大寨6.28特大滑坡碎屑流災害,造成99人死亡及失蹤。通過調查類似地質條件下該地區地質災害隱患分佈情況。以該地區大田小學崩塌為代錶分析該類型危巖帶形成的原因及形成機理,分析瞭危巖體穩定性及髮展趨勢,併運用rockfail軟件對滾石運動路徑、影響範圍、彈跳高度、運動能量做瞭分析。結閤該地區自然條件,提齣瞭相應的防治建議。對該地區類似崩塌(危巖)的防治,有一定的藉鑒作用。

Because of special geological conditions in north of Guanling, the large-scale debris avalanche in Yongwo Dazhai of Gangwu town was caused in 28 June, 2010, and 99 people were dead (or missing) by this disaster. After this disaster, we have surveyed the distribution characteristics in similar geological conditions to this disaster. This paper takes the debris avalanche of Datian Primary School as an example, and analysis the cause and mechanism, the stability and trend of the unstable rock belt, then studies the rolling rock-bodies’ movement path, influence area, bounce height, kinetic energy by software of Rockfail. Based on the research results and the natural conditions, this paper proposes the corresponding measurements for preventing these similar disasters, which is reference to the similar disaster of other areas.
