Hoek-Brown准则下岩质边坡的GSI反演
Back analysis of rock slope GSI magnitude under Hoek-Brown criterion
摘要
Abstract
For slope in closely jointed schist rock mass,the equation of the slid surface was solved by the limit analysis upper bound theorem under Hoek-Brown criterion.The relationship between GSI and the slid surface depth was analyzed and the change law of slid surface with γ and H was plotted.The results show that the GSI can be back analyzed utilizing the slid surface depth.Finally,a example proves the effectiveness of this method.关键词
