Abstract

Abstract

The study of thermal-mechanical coupling mechanism is of great significance to deep rock engineering such as rock tunnel fire, nuclear waste treatment and geothermal development. To investigate the effect of high temperature on the impact mechanical properties of granite, the real-time high temperature impact compression test was carried out on the granite specimen at 20～800 ℃. The Caledonian granite in the construction area of Sejila Mountain on Sichuan-Tibet Railway was taken as the research object, real-time high temperature impact compression tests were carried out on the specimens under five different temperatures ( 20, 200, 400, 600 and 800 ℃) with three average loading rates ( 72.8, 144.97 and 230.29 s⁻¹) by using the split Hopkinson pressure bar (SHPB) and synchronous box-type resistance furnace. The effects of high temperature and loading strain rate on the fracture characteristics, dynamic compressive strength and fractal dimension of the specimens were analyzed. The variation law of dissipated energy per unit volume was also studied and discussed. In addition, the intrinsic correlation between the change of mineral composition and the dynamic strength of granite was analyzed based on X-ray powder crystal diffraction. The results show that the brittle fracture of the specimens at 20 to 400 ℃ is dominant, and the fragments are spindle-shaped with sharp ends. The specimens at 600 ℃ are dominated by plastic failure, and their shapes tend to be round. The peak stress of specimens increases first and then decreases with the increase of temperature, reaches the strength threshold at 200 ℃, and then decreases continuously. The dissipated energy per unit volume of rock has a positive linear correlation with the loading strain rate and a quadratic function with the temperature, which shows a good fitting effect. The content fluctuation and phase change of the three main mineral components of quartz, mica and feldspar lead to the gradual deterioration of the dynamic strength of granite after 200 ℃.
