摘要
论述了目前研究岩石尺寸效应计算模型所存在的不足,结合大红山铜矿岩石力学试验结果,提出了改进的岩石尺寸效应的计算式,探讨了岩石试件推荐值和岩体强度的计算方法及弱化方法。
The existing deficiency of calculation model for rock size effect research is discussed in this paper,the improved calculation method of rock size effect is proposed combining with the test result of rock mechanics in Dahongshan Copper Mine;and the recommended value of rock sample,as well as the calculation method and weakening method of rock mass strength are discussed too.
