摘要: 2017年6月24日上午6时左右，四川省茂县叠溪镇新磨村发生特大高速远程滑坡。这次山体滑坡掩埋了64座房屋，造成10人死亡，另有73人失踪。这是近年来中国发生的最严重的灾难性山体滑坡事件之一，引起了国内外公众和学术界的广泛关注。高速远程滑坡是一种典型的滑坡，因为运动速度快，距离长而得名，其高速启动机理和运动特征一直是地质灾害领域研究的热点问题，而四川茂县新磨村滑坡就属于典型的高速远程滑坡–碎屑流。本文以四川省茂县叠溪镇新磨村滑坡为研究对象，通过资料收集、详细的现场调查和数值模拟，对滑坡的特征和成因机制进行了简单的分析和研究。其次，建立了新磨村滑坡的地质模型，借助DAN-3D数值软件，进行滑坡运动过程模拟。将模拟后的运动特征与堆积形态与真实情况对比，发现两者基本一致，由此得出结论，DAN-3D数值模拟可以较为真实地还原滑坡运动过程，从而可以对其它滑坡进行早期模拟与预测，以期为滑坡的识别和防治提供技术支撑。
Abstract: At around 6 am on June 24, 2017, a huge high-speed remote landslide occurred in Xinmo village, Diexi town, Mao County, Sichuan province. The landslide buried 64 homes, causing 10 deaths and leaving 73 others missing. It was one of the worst catastrophic landslides to occur in China in recent years, and has attracted wide attention from the public and academia at home and abroad. High speed and long distance landslide is a typical type of landslide, which is named for its fast moving speed and long distance. Its high speed starting mechanism and moving characteristics have been a hot topic in the field of geological disasters. The Xinmo village landslide in Mao County, Sichuan Province is a typical high-speed and long-distance landslide-debris flow. Taking Xinmo village landslide in Diexi Town, Mao County, Sichuan Province as the research object, this paper makes a simple analysis and study on the characteristics and genetic mechanism of the landslide through data collection, detailed field investigation and numerical simulation. Secondly, the geological model of Xinmo village landslide is established, and the landslide movement process is simulated with the help of DAN-3D numerical software. Comparing the simulated motion characteristics and accumulation patterns with the real situation, it is found that the two are basically consistent, and the conclusion is drawn. DAN-3D numerical simulation can restore the real landslide movement process, so that other landslides can be simulated and predicted in the early stage, in order to provide technical support for landslide identification and prevention.
