Soil body electrical parameter space-time distribution testing device and method for triaxial experiment

The invention provides a soil body electrical parameter space-time distribution testing device and testing method for a triaxial experiment. The testing device comprises a triaxial compression experiment device, an insulating rubber film, conducting strips and an electrodes. The insulating rubber film, the conducting strips and the electrodes are added into a confining pressure chamber in the triaxial compression experiment device; the insulating rubber film is used as a soil sample to be isolated from the confining pressure chamber in the triaxial compression experiment device; the conductingstrips and the electrodes are used for testing electrical parameters of the soil body; the conducting strips are arranged at the end parts of the two ends of a soil sample of the triaxial compressionexperiment; the electrodes are inserted into the soil body through the small holes of the insulating rubber film and are uniformly arranged along the circumferential direction of the insulating rubber film to form a group of
