根据现场勘探资料、室内试验数据,并综合考虑边坡工程施工特性等因素,在某矿区不同层位岩石的大量实验的基础上,利用3种不同的岩体强度折减法(中小值与中大值强度折减法、内摩擦角折减系数法、工程经验系数折减法)分别计算了该矿区的岩体强度,并用信息熵赋权法综合确定了边坡工程岩体的力学参数和变形指标,为分析和评价矿山边坡工程的强度及变形稳定性提供了基础数据。
Based on the field exploration data and laboratory test data and comprehensively considering the construction characteristics of the slope engineering and other factors, based on a large number of experiments on rocks in different layers in a mining area, three different methods of strength reduction of rock mass (middle and small and medium large The value of strength reduction method, the reduction coefficient of internal friction angle method, the reduction of engineering experience coefficient method) were calculated rock mass strength of the mine, and using information entropy weight method to determine the slope rock mass mechanical parameters and deformation indicators for the The basic data is provided for analyzing and evaluating the strength and deformation stability of the mine slope engineering.
