The heat-treated granite samples were prepared for testing.According to the standard requirements of the International Society of Rock Mechanics（ISRM）[26]，the samples were made into cylinders with dimensions of d50 mm×50 mm and d50 mm×100 mm，respectively，by cutting and polishing，controlling parallelism within±0.05 mm and the surface flatness within±0.02 mm.Samples of similar wave velocity were selected，numbered and heated to the designed temperatures.As shown in Fig.1，the rock sample is mainly composed of quartz，biotite and potassium feldspar.After initial trials in which the static strengths given in Table 1 were taken into consideration，the appropriate incident energy is around 60 J，and the air pressure is about 0.6 MPa.
