中文摘要：
采用6种不同风化程度的花岗岩试样,在相同围压下进行了不同加载速率（1～105 MPa/s）的动三轴压缩实验。研究发现,不同风化程度花岗岩试件的抗压强度、弹性模量均随加载速率的增加而增加,泊松比随加载速率的增加而减小。抗压强度的增加幅度随风化程度的增加而增加,弹性模量的增加幅度基本保持不变。
英文摘要：
Dynamic triaxial compressive tests for different weathering degrees granite were conducted with loading rates 1-105 MPa/s and confining pressure 3 MPa.The results show that the compressive strengths of the different weathering degrees granites are all increase with the increasing of the loading rate;and the increment of the compressive strength increases with the increasing of the weathering degree.The Young＇s moduli of the different weathering degrees granite are all increase with the increasing of the loading rate;and the increment of the Young＇s modulus remain unchanged with the increasing of the weathering degree.The Poisson＇s ratios of the different weathering degrees granites are all decrease with the increasing of the loading rate.
