| 摘 要： | 为了解锦屏一级水电站坝基绿片岩的流变力学特性，采用岩石全自动流变伺服仪对绿片岩进行了三轴压缩流变试验。基于试验结果，研究了绿片岩在不同围压作用下的轴向应变以及侧向应变随时间的变化规律，讨论了流变特性对岩石应力一应变曲线的影响，探讨了不同应力水平下的轴向以及侧向流变速率变化趋势，分析了不同围压下流变的破裂机制，掌握了绿片岩三轴流变的基本规律，从而为该水电站工程流变数值分析时参数的辨识提供了可靠的依据。 |

| Abstract: | In order to know about the rheological properties of greenschist specimen in Jingping First Stage Hydropower Project, triaxial compression rheological experiments with greenschist spceimens were carried out on the rock servo-controlling rheology testing machine. Based on the triaxial rheological experimental results, the variance law of axial and lateral strains of greenschist specimens with the time under different confining pressures is investigated. The effect of rheological properties on the stress-strain curve of greenschist is also discussed. At the same time, the variance tendency of axial and lateral rheological rates under different deviatoric stresses is discussed in detail; and rheological failure mechanism under different confining pressures is also analyzed. The triaxial rheological law of greenschist specimen is mastered, which brings important reference for the identification of parameters when carrying out the rheological numerical finite element analysis of this hydropower project. |
