| 英文摘要 | The structural plane plays a decisive role in the development processes of rockburst. In this paper, Barton-Bandis criterion of structural plane and its conversion relationship with Mohr-Coulomb criterion are discussed in detail. Firstly, when the structural plane obeys Barton-Bandis criterion, the value range of the dip angle of the structural plane when it is yield is deduced theoretically, and the yield function of the structural plane is proposed: F = sin (A - 2 beta) + P sin A. The correctness of the theoretical derivation result is verified by a mapping method and numerical simulation method. Secondly, based on the result of theoretical derivation and assuming that rock obeys Mohr-Coulomb criterion, a fast identification method for the failure modes of rock mass is proposed. The failure modes of rock mass are divided into no failure, failure along structural plane, failure along rock, and failure along both rock and structural plane, and the correctness of the fast identification method is verified by numerical simulation. Finally, from the perspective of structural plane failure, a new method for converting Barton-Bandis criterion to Mohr-Coulomb criterion is proposed. Based on the yield of structural plane and relative error of displacement, the differences between the new method and existing conversion methods are compared. The results show that the yield condition determined by the new method is consistent with those determined by Barton-Bandis criterion, and the relative error of displacement is less than the tangent regression method and linear fitting method. In summary, the relevant methods and conclusions of this paper provide theoretical support and technical guidance for the mutual conversion between different criteria and the prediction and identification of rock mass failure modes in rockburst. |
