| 摘 要： | 基于热力学框架下的Perzyna粘塑理论,推导了适用于岩石的流变粘弹塑性本构模型,结合砂岩的三轴蠕变试验数据,对推导的本构模型的合理性与正确性进行了验证.结果表明:基于粘塑理论的流变本构模型可以较好地反映岩石的流变力学特性,对室内试验结果拟合得到的相关力学参数可以作为现场岩体流变力学特性评价的参考依据.

| Abstract: | This article is based on thermodynamic framework Perzyna viscoplastic derivation theory,as applied to the rock of visco-elastic-plastic constitutive model,combined with sandstone Triaxial creep test data,on the deduction of constitutive model of rationality and validity has been validated.Results： theory based on viscoplastic constitutive model of evolution to better reflect the rheological and mechanical properties of rocks,on test results obtained relevant mechanical fitting parameters can be used as live rock rheological mechanics characteristic evaluation of reference basis. |
