摘要
在考虑应力偏量作用下的蠕变参数损伤演化规律基础上建立了岩石蠕变损伤模型,对FLAC3D(vision 3.0)中Cvisc模型进行了二次开发,通过数值模拟验证分析砂岩试样蠕变特征,进一步完善了材料的流变模型。
This paper established the rock creep damage model based on the creep parameter damage evolution law under the consideration of stress deviation,made secondary development to the Cvisc model in FLAC3 D（ vision 3. 0）,through the numerical simulation verified the creep characteristics of sandstone specimen,then further perfected the rheological model of materials.
