| 摘 要： | 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。

| Abstract: | According to the exploration data and results of indoor tests on rock samples from various strata in some mine,and based on a synthetic consideration of the characteristics of slope engineering construction,the strength of rock in the mine was calculated using three kinds of rock strength reduction methods,including medium-small value and medium-large value method,inner friction angle reduction factor method as well as engineering empirical factor strength reduction method,the mechanical parameters and deformation index of slope rock were determined by use of the information entropy weighting method,which provided essential data for analysis and evaluation of strength,deformation and stability of slope engineering in the mine. |
