The invention discloses a true triaxial test system for testing rock. The true triaxial test system comprises a main machine framework, wherein a work cavity is formed in the main machine framework, atesting chamber for accommodating a rock sample to be tested is arranged in the work cavity, and a plurality of the lateral sides of the testing chamber abut against the work cavity of the main machine framework. The true triaxial test system further comprises a plurality of sets of compensation type pressurizing devices, wherein the pressurizing devices are sleeved in the work cavity and act onthe testing chamber. At least one set of the compensation type pressurizing device is arranged on any lateral side not abutting against the work cavity of the main machine framework of the testing chamber, the compensation type pressurizing devices are used for exerting constant acting force in one direction on the rock sample in the testing chamber, and constant acting force generated by the different sets of the compensa
