Abstract

The invention discloses a method for judging tunnel tension fracture slippage type rock burst which comprises the following steps: establishing a tunnel tension crack slip type rockburst mechanical model according to a tunnel tension crack slip type rockburst generation mechanism; obtaining a potential function and a balance curved surface calculation formula of a system formed by the tension fracture slip type rockburst slip rock mass and the soft layer according to the tunnel tension fracture slip type rockburst failure mechanical model and the rock mass soft layer constitutive relation; analyzing the system stability of the tension fracture sliding type rock burst problem by adopting a folding mutation model; and based on a folding mutation theory principle, judging the tunnel tension crack slip type rock burst. The method for judging the tunnel tension fracture slippage type rock burst based on a folding mutation theory has important significance in effectively preventing and controlling rock burst.

Description

technical field [0001] The invention belongs to the technical field of underground engineering, and relates to a method for judging a rockburst of a tunnel tension-crack slipping type. Background technique [0002] With the development of social economy and the consumption of shallow resources, underground engineering construction and resource development are gradually moving to deep, showing the development trend of "long length, large quantity, large cross-section, and deep burial". Deeply buried underground projects often have higher in-situ stress levels due to the increase in burial depth. For example, the diversion tunnel of the Jinping II Hydropower Station has a maximum buried depth of 2525m and a maximum in-situ stress of 72MPa; The stress can reach 56.6MPa, and increases linearly with the increase of buried depth; the maximum buried depth of Xikang Qinling Railway Tunnel is about 1600m, and the maximum ground stress is about 86.2MPa. In addition, although there ar...
