Deep rock strength evaluation method and device and storage medium

The invention belongs to the technical field of deep rock strength evaluation, and particularly relates to a deep rock strength evaluation method and device and a storage medium. According to the method, the uniaxial compressive strength sigma c of the rock is obtained through a uniaxial compression test of the rock, and the initial internal friction angle # imgabs0 # and the fitting parameter B of the rock are obtained through triaxial compression test data of the rock under a plurality of medium and low confining pressure conditions. The stress state of the kind of rock in an actual structure is obtained through a test or calculation, and the first principal stress sigma 1 and the third principal stress sigma 3 of the rock are calculated. And substituting the uniaxial compressive strength sigma c, the initial internal friction angle # imgabs1 # fitting parameter B and the third principal stress sigma 3 into a corrected strength criterion to obtain critical strength # imgabs2 #, and comparing the first princ
