| 摘 要： | 改进制作了一种双轴岩石平面应变实验装置,并自行设计制作了侧向加力器。该装置不仅能施加合适的围压,而且能在实验过程中动态监控围压的变化。对砂岩的实验测试研究表明,这种改进后的双轴岩石平面应变仪能更好地模拟岩石平面应变的条件,具有较好的实用性。

| Abstract: | A biaxial plane-strain apparatus for investigating the deformation and failure features of rock is improved and constructed on a passive stiff-frame concept;furthermore,a new device inducing confinement on both sides of the prism specimen was designed and built,which can not only impose varying confining pressure on the specimen,but dynamically monitor the change in confinement due to deformation of the specimen during testing.Theoretical analysis and test results show that for rock specimens with Young's modulus below 14.16GPa,the apparatus can provide an acceptable plane-strain condition and be of practical use. |

| Keywords: | biaxial plane-strain apparatus for rock confinement inducing transducer stiffness |
