To study the evolution laws and its suffered influential factors of thermal effects and shock waves generated by TBX explosion around the tunnel entrance， field tests at and out the tunnel entrance were carried out. The thermal effect parameters （e.g.， fireball size and temperature）， and the parameters of shock waves （e.g.， overpressure peak， positive pressure time， specific impulse， and waveform）， were analyzed. Moreover， the propagation trace inside the tunnel of shock wave was analyzed in conjunction with the results of Trinitrotoluene （TNT） tests. The results indicate that， the intensity of Aluminum （Al） afterburning is higher in the mode of the air explosion， and thermal effect and shock wave power are higher than them in the mode of the surface proximity explosion when the TBX is detonated at the tunnel entrance. Regarding thermal effects， the height and peak temperature of the fireball generated by the explosion are approximately 2 and 1.41 times higher， respectively， than those of the surface proximity explosion. The peak temperature measured by the thermocouple inside the tunnel is about 2.42 times higher than that of a surface proximity explosion， and the heat flux density can exceed 19.3 times that of the surface proximity explosion. The temperature increase effect generated by Al afterburning under air explosion conditions becomes more significant with the increase in explosive charge. Concerning shock waves， the pressure wave generated by Al afterburning under air explosion conditions at the tunnel entrance is stronger than that of the surface proximity explosion， and the reflection and superposition paths of shock waves are more complete. Compared to the surface proximity explosion， the equivalent coefficients of overpressure peak， positive pressure time， and specific impulse of the shock wave under air explosion conditions are approximately 1.3， 1， and 1.1， respectively. The evolution laws of thermal effects and shock wave effects are influenced by the combined effects of the tunnel constraint and the intervention of the ground surface. Under conditions of the air explosion， the constraint effect of tunnel is more pronounced， and the afterburning effect is more significant. However， under conditions of surface proximity explosion， the intervention effect of the ground surface can weaken the constraint effect of tunnel， and the mixing between Al powders and air can be suppressed， resulting in a reduction of afterburning intensity.
