摘    要:本文根据东乡铜矿砂质页岩的单轴压缩蠕变试验结果,将稳定蠕变变形分解为粘弹性变形和粘塑性变形,并建立了二者与应力和时间的关系,进而讨论了粘弹性模量和粘塑性模量,粘弹性应变速率和粘塑性应变速率,以及应变延迟时间等问题。

关 键 词:蠕变变形  定常蠕变  蠕变试验  压缩蠕变  岩石试验  蠕变分析  应变分量  粘弹性  粘塑性  形变模量/软弱岩石

Abstract:Based on the results obtained from the uniaxial compression creep tests of thesandy shale specimens of Dongxiang Copper Mine,stable creep strain is separatedinto visco-elastic and visco-plastic strains,and the relationships between visco-elastic strain and stress and time,and between visco-plastic strain and stress andtime have been established in this paper.Furthermore,on this basis,severalcharacteristic parameters for stable creep,including visco-elastic and visco-plasticmoduli,visco-elastic and visco-plastic strain rates,strain retardation time etc.arediscussed.
Keywords:Deformation of creep  steady state creep  creep tests  compressive creep  rock test  creep analysis  components of strain  viscoelasticity  viscoplasticity  deformation modulus/weak rock
