Darong landslide that occurred in Cengong County in June 29, 2012 was a large scale and sudden landslide hazard. The volume of landslide was about 3100000 cubic meters, and it caused great damage. Being located in the instable ancient landslide accumulation area, Darong landslide was mainly caused by local unreasonable artificial fill and strong rainfall. First of all, we should take measures to obviate dangers during the emergency rescue, and gradually implement comprehensive emergency control measures. The accumulation of landslide also needs to implement long-term monitoring. Research on the mechanism of Darong landslide had an important reference for the determination of the similar slope stability in the province.%2012年6月29日岑巩县发生的大榕滑坡为突发性大型滑坡灾害，约310万方，并堵塞前缘河流，危害严重。大榕滑坡为古滑坡堆积区失稳，主要由局部不合理的人工填土和强降雨作用共同导致。应急抢险中，首先应及时排险，并逐步实施综合性应急防治措施。滑坡堆积体还需实施长期监测。大榕滑坡失稳机制研究对省内类似斜坡稳定性判断和分析具有重要参考价值。
