Abstract

Deep rock engineering is in a high stress disturbance environment，and high temperature must be taken into consideration，dynamic compression characteristics are important for evaluating the stability of surrounding rock，which is different from the shallow. In order to get the dynamic mechanical properties of rock suffered both temperature and water. By using the system of Hopkinson pressure bar，dynamic uniaxial compression tests of Fangshan marble in dry and saturated conditions are carried out in four temperature gradients(25 ℃，105 ℃，450 ℃，700 ℃). The dynamic compression characteristics of small porosity rock under the action of temperature and water are studied. The results show that the longitudinal wave velocity increases at first and then decreases，and starts decline sharply after 450 ℃. The dynamic uniaxial compression strength of dry and saturated marble gradually increases linearly with the increases of loading rate in every temperature，and rock after temperature damage is more obvious than room temperature. Compression strength of thermal damaged rock assumes a downward trend as the temperature increases. The compression strength of saturated specimens is almost same as dry specimens in 105 ℃，and the dynamic compressive strength of saturated rock is higher than that of dry rock at 450 ℃，while the strength of saturated specimens can be higher than dry ones when loading rate(after 1 500 GPa/s) is high enough in 700 ℃.

Key words： rock mechanics water condition thermal damage split Hopkinson pressure bar(SHPB) Fangshan marble
