The invention relates to a device and a method for testing the bearing capacity of a basalt fiber rib anchor cable under a stress confinement condition. The testing device comprises a sample chamber stress loading system, a sample chamber fixing system, a sample chamber system, an experimental sample, a drawing system and a data acquisition system. The sample chamber stress loading system is used for applying stress to a sample and simulating different stress confining conditions; the sample chamber fixing system is mainly used for fixing the sample chamber on the drawing system; the sample chamber system is mainly used for mounting and placing experimental samples in the bearing capacity test of the basalt fiber bar anchor cable; the drawing system is mainly used for tension tests of experimental samples under different stress confinement conditions and testing the bearing capacity of the basalt fiber bar anchor cable. The data acquisition system can be used for collecting confining pressure, tensile force a
