采动斜坡变形破坏模式分析及预测

Analysis on Deformation and Failure Model of Excavating Slope and Prediction

介绍了国内一些学者在这方面的研究方法。考虑地下开采方向与斜坡岩体结构类型的不同组合,探讨了斜坡的变形破坏模式。根据采动斜坡的变形破坏特点,提出可以采用最初用于预测生物增长规律的费尔哈斯特模型来描述斜坡的变形趋势,在对国内某斜坡的预测实践中,发现该模型具有良好的适应性,能够有效的预测采动斜坡的变形趋势。

Some research methods of Chinese scholars in this field are introduced Slope deformation and failure models are discussed in the light of various combinations of mining direction and rock slope structure According to deformation characteristics of excavating slope, the paper suggests that we can adopt Verhulst model that firstly described the law of population growth to describe slope deformation trend In the practice of predicting the deformation of a certain excavating slope in China, it is testified that Verhulst model is of a good adaptability With this model, trend of excavating slope deformation can be effectively predicted
