中文摘要: |
基于岩石应变强度理论和岩石强度的Weibull分布假设,引出能合理描述岩石微元强度的参量,采用损伤力学理论,建立了能够反映残余强度的单轴压缩下岩石损伤统计本构理论模型.并利用伺服控制试验系统(RMT-150B)对石灰岩进行了单轴压缩试验,得到合理的石灰岩损伤统计本构关系,并验证了理论模型。 |
英文摘要: |
Based on the strain strength theory and the Weibull distribution hypothesis of rock strength, this paper developed the parameter that can rationally describe the micro-unit strength of rock.And a statistical constitutive model for rock damage under uniaxial compression, which can reflect the residual strength of rocks, is established by use of the damage constitutive theory of continuous medium . With the RMT-150B electro-hydraulic and servo-controlled testing machine, uniaxial compression tests are performed on the limestone rock, and the parameters of the damage statistical constitutive model are determined according to the experimental results, and results are obtained about the statistical constitutive model for limestone rock damage. |
