| 摘 要： | 阐述了岩体力学参数研究的重要性，系统地介绍了几种国内外常用的岩体力学参数的确定方法及其原理。以云锡大屯锡矿岩体力学参数研究为例，并以其室内试验得出的岩石物理力学参数和岩体质量评价RMR值为基础，采用这些方法对岩石物理力学参数进行工程折减弱化处理，计算得出其岩体力学参数。其结果对比分析及其推荐值的工程应用结果表明：将最新的Hoek-Brown准则、室内试验、M.Georgi法和费森科法四者相结合来进行分析，得出的岩体力学参数更为合理，提高了工程岩体力学计算精度。

| Abstract: | The importance of study on mechanical parameters of rock mass is elaborated, and some methods and their principles that are often used to determine rock mass mechanical parameters at home and obroad are introduced systematically. Then taking the research of rock mass mechanical parameters from Yunxi Datun Tin Mine for example, based on the rock physico-mechanical parameters which were obtained by indoor laboratory test and the rock mass quality evaluating RMR value, the rock mechanical parameters are reduced and attenuated by these methods; and the results of rock mass mechanical parameters are obtained．The comparative analysis of the results and project application results of recommended values show that：the latest Hoek-Brown criterion, laboratory test, M. Georgi method and Г.ΦИCEHKO method are combined to study and analyze, so that the rock mass mechanical parameters obtained are more reasonable, and computational accuracy of the project rock mass mechanical parameters may be improved. |
