Claim Text:
1. An experimental method for simulating an impact rockburst, the method comprising: S1: making a rock sample specimen having a through hole or a half hole; S2: loading initial static stresses of three directions onto the rock sample specimen, and maintaining the initial static stresses of the three directions, to simulate a situation that an excavated tunnel suffers the static stresses; S3: loading dynamic load(s) of one direction, two directions or three directions onto the rock sample specimen by 0.5-10 minutes, so as to determine whether a spalling phenomenon appears on an internal surface of the through hole or the half hole, wherein the dynamic load is used to simulate the disturbance wave induced by an excavation, a blasting, an earthquake or a mechanical vibration; S4: under an action of the dynamic load in the step S S5: under the action of the dynamic load in the step S
