Abstract Impact mechanical performance experiments are carried out for marble after different high temperatures under dynamic loading by using split Hopkinson pressure bar(SHPB) equipment. The stress-strain curves of specimens under impact loading are obtained. The temperature effects on the longitudinal wave velocity，as well as the peak stress，peak strain and elastic modulus of marble under impact loading are analyzed. It is demonstrated that the longitudinal wave velocity declines linearly with the increase of temperature. When the temperature is below 800 ℃，it does not remarkably affect the peak stress. When the temperature is above 800 ℃，the peak stress decreases obviously with temperature increasing. Meanwhile，the peak strain increases slightly with temperature increasing when the temperature is below 600 ℃，but the peak strain increases linearly with temperature increasing when the temperature is above 600 ℃. The elastic modulus under different impact velocities present the same change rule with temperature variation，decreasing approximately linearly with temperature increasing. The experiment results can be analyzed from the aspect of the changes in microstructural characteristics of marble after different temperatures.

Key words： rock mechanics high temperature marble longitudinal wave velocity impact mechanical behaviors
