| 英文摘要 | In order to reveal the disaster mechanism of hydraulic fracturing for hydraulic tunnel, force analysis of hydraulic tunnel and research on crack propagation is combined in this paper. Theory of Stress Intensity Factor is introduced into the analytical solution as the criterion of crack propagation. Dividing cracks into shear-tensile and shear-compressive types, formulas calculating critical inner water pressure of crack propagation for hydraulic tunnel are attained. On the basis above, the influence of geological condition (rock cohesion and friction angle, geostress and pore water pressure) on the critical water pressure of hydraulic tunnel is analyzed. The computation results show that increases of both cohesion and friction angle for rock mass are advantageous to prevent occurrence of crack propagation on the tunnel wall. The more prominently pore water pressure influences, the more easily cracks of both shear-tensile and shear-compressive types propagate and the more disadvantageous stability of hydraulic tunnel will be. Moreover, with the geostress diminishing, cracks will be more likely to expand. |
