摘要
采用改进的岩石热粘弹性流变模型研究了我国甘肃北山花岗岩在温度影响下的流变特性,给出了流变模型参数在不同温度和时间影响下的变化规律,分析了北山花岗岩蠕变参数(蠕变柔量、蠕变行为时温影响因子、延迟时间)和松弛参数(松弛模量、温度对松弛行为的影响因子、松弛时间)及其随温度的变化规律。
The rheologic characteristics of Beishan granite from Ganshu Province under temperature effect are analyzed with thermo-viscoelastic rheological model for rock.The numerical values of model parameters under different temperature are presented and the variation laws of them along with temperature are gained.Creep parameters(including creep compliancei,nfluencing factors of time and temperature to creep,delay time of creep) and relaxation parameters(including relaxation modulusi,nfluencing factor of temperature to relaxationr,elaxation time) are analyzed and variation laws with temperature are acquired.Some conclusions are provided for the design of storeroom for nuclear waste.
