基于波动量化评估指标体系的露天石灰岩矿山边坡稳定性研究OA

This paper takes the typical open-pit limestone mine slope in eastern Hubei as the research object,introduces fluctuation quantification analysis into the dynamic evaluation of slope stability,constructs a fluctuation quantification evaluation index system of"quantity dimension standard deviation(SD)+shape dimension rotation angle(RA)",accurately depicts the slope displacement fluctuation characteristics from the dual dimensions of numerical discretization and geometric morphology,and systematically extracts the slope displacement fluctuation characteristics and identifies key influencing factors based on Beidou GNSS displacement time series monitoring data.Based on the fluctuation quantification evaluation index system,this paper analyzes the dynamic impacts of natural factors such as precipitation and human factors such as mine blasting on the displacement fluctuation of limestone open-pit mine slopes,explores their fluctuation characteristics,and provides new ideas and methods for the study of slope stability in open-pit limestone mines,which has certain theoretical and practical value.
