摘要描述岩石流变损伤常用的方法一般局限于加速流变阶段，并未考虑初始流变和稳态流变阶段的损伤，这与大量的试验研究结果相悖。为更好地描述岩石流变三阶段的损伤流变，基于室内试验结果与损伤理论，以Burgers模型、Mazars的损伤演化方程为基础，提出考虑流变全过程损伤的流变损伤本构模型，进行参数辨识，并验证所提出模型的合理性。在此基础上，采用FLAC3D软件，对苏州凤凰山隧道的围岩变形进行计算，对比分析现场监测数据和考虑损伤的流变模型及不考虑损伤的流变模型围岩的变形情况。结果表明，采用的流变损伤本构模型数值计算结果更加接近现场监测值，能够更好地反映洞室围岩的流变变形及损伤特性，因此考虑全过程损伤的流变模型是合理的。

Abstract：Common method of describing the rheological damage is usually limited to the accelerated rheological stage，and damage in the decay and steady rheological stages are not considered，which contradict lots of experimental results. In order to better describe three stages of rock rheology，a rheological damage constitutive model for sandstone is proposed by using the damage theory and by introducing the concept of the whole process of damage into Burgers rheological model based on the Mazars damage evolution law. The validity of the model is verified and the parameters are determined by fitting the triaxial rheological test data. Then，the model is applied to the Phoenix Mountain Tunnel project by using the fast lagrangian analysis of continua in three- dimention(FLAC3D). The field monitoring data are compared to the model prediction using the proposed rheological damage model and the rheological model without damage. Results show that the numerical prediction using the proposed model agrees well with the field measurements and describes well the damage and rheological properties of surrounding rocks of the tunnel. Accordingly，the rheological damage model considering the whole process of damage is reasonable.
