摘要:
以云南某露天矿采场岩质高边坡工程为研究对象,阐述了岩体力学参数在边坡稳定性分析中的重要
性,因原位试验对于坚硬岩体或极软岩体的不适用性,对坚硬岩体,以室内试验得出的岩石物理力学参数和
岩体质量评价RMR评分值为依据,并综合考虑岩体中节理裂隙、岩体结构、地下水的影响,运用霍克-布朗
(Hoek-Brown)强度准则将岩石力学参数进行折减修正后换算成岩体力学参数,并与现场原位试验所得软弱
岩体力学参数结果相结合得到最终岩体力学参数.在上述调查、研究基础上,采用有限差分法(FLAC数值分
析软件)对现状边坡进行静态的稳定性分析,提出合理的最终边坡角及总台阶高度,保证矿山正常生产和经
济效益的提高
Abstract:
With an open pit mining of the Yunnan high rock slope engineering field as a research object,the paper described
the mechanical parameters of rock slope stability and the study of importance of the in situ test for hard rock or soft rock
does not apply nature of hard rock.Laboratory experiments with the mechanical parameters of rock and rock mass quality
rating is based on RMR.Considering the fractured rock mass,rock mass structure,the impact of groundwater,the use of
Hawk-Brown(Hoek-Brown)rock strength criterion parameters will be amended and converted into a reduced rock mass
parameters are derived.In situ testing and on-site mechanical parameters of soft rock from the combination of the final
results of rock mechanics parameters.In the survey,based on research using the finite difference method(FLAC numerical
 analysis software)on the status of static slope stability analysis,a reasonable final slope angle and the total step height
is obtained to ensure normal production and economic benefits of mining to improve.
