Study on Triaxial Creep Experiment of Beishan Granite under Low Confining Pressures

Ma, Li Ke / Li, Yun Feng / Zhao, Xing Guang

Time-dependent brittle deformation is a foundational process operating in the underground engineering. So, the study of its characterization is essential to the design and construction of excavations in the rocks for high level radioactive waste disposal repositories. In this study, three constant stress tests under different confining pressures were performed on specimens of Beishan granite. Based on the laboratory results, we investigated mechanical creep behavior of Beishan granite under low confining pressures and compared the results with previous investigations.
