description abstract | Rock mechanics parameters for underground engineering cannot be rapidly or comprehensively tested on site; thus, this article presents a method for determining rock mechanics parameters using drilling parameters obtained during a field drilling experiment. Based on the rock fracture characteristics, a rock-cutting mechanical model was developed that does not assume a damaged rock surface. In this model, the ultimate load of the rock under an oblique cutting force is derived based on slip-line theory. The relationship between the cutting torque and the rock mechanics parameters (hereafter referred to as the CT-R relationship) is then obtained. The results of laboratory tests were compared with theoretical analysis, and the mean deviation ξ was 16.8%, verifying the rationality of the rock-cutting mechanical model and the CT-RP relationship. The CT-RP relationship established in this article can provide a theoretical basis for the inversion of the rock mechanics parameters by the drilling parameters. | |
