摘要
我国露天矿山的开采深度不断加大,导致了高陡边坡及滑坡事故增多。在分析边坡稳定性影响因素的基础上,对目前边坡稳定性分析常用的方法进行了总结,介绍了极限平衡分析法和可靠性分析法。从滑坡的空间、时间、强度三方面对滑坡预报预警的十余种模型的应用类型、使用方法及预警判据进行了详细归纳,并对Verhulst模型法和人工神经网络法做了重点介绍,为滑坡预警技术的研究提供重要的依据和理论支持。最后,分析并总结了露天矿山高陡边坡滑坡预警的研究趋势。
With the increasing depth of open-pit mining in China, more and more high and steep slope and land- slide accidents have occurred. Base on the analysis of influence factors of slope stability, the common methods of slope stability analysis at present were summarized, including limit equilibrium analysis method and reliability anal- ysis method. The application type, usage method and warning criterion of more than ten kinds of landslide forecast warning models were summarized from three aspects of landslide ： space, time and intensity, and the Verhulst mod- el method and artificial neural network method were focused on, which provides important basis and theoretical sup- port for landslide early warning technology. Finally, the trend of landslide warning for high and steep slope of open pit mine was analyzed and summarized.
