通过高温下的单轴和三轴抗压蠕变试验，研究了三峡花岗岩单轴应变和粘聚力随温度和时间的变化响应，反映了温度和时间对三峡花岗岩变形特性和强度特性的影响规律；提出了拟合三峡花岗岩单轴应力－应变关系和变形特性的力学模型及其粘聚力随温度和时间变化的经验公式。
Through the uniaxial and triaxial compression creep tests at high temperature, the response of uniaxial strain and cohesion of the Three Gorges granite to temperature and time is studied, which shows the influence of temperature and time on the deformation and strength characteristics of the granite in the Three Gorges The mechanical model and the empirical formula of the cohesion with the temperature and time of the uniaxial stress-strain relationship and the deformation characteristic of the Three Gorges granite are proposed.
