Claim 1:
2. The thermal-stress-pore pressure coupled electromagnetic loading triaxial Hopkinson bar system according to claim 1, further comprising a pore pressure loading apparatus; the pore pressure loading apparatus comprises the left pore pressure pipe and the right pore pressure pipe, wherein diameters and lengths of the left pore pressure pipe and the right pore pressure pipe are both the same; the left pore pressure pipe and the right pore pressure pipe are built in a right end of the left stress wave loading bar and a left end of the right stress wave loading bar respectively, and directly contact loading ends of the test specimen; when a pore pressure is applied, a pore liquid with a preset pressure is injected into the left pore pressure pipe; the pore liquid, under a drive of the pore pressure, passes through internally connected pore throat channels inside the test specimen, and is discharged from the right pore pressure pipe; and the pore pressure is maintained constant at a preset value.
