- W2384349764 abstract "Based on the fact that fractured rock mass is prevalent in rock engineering,the fractured rock mass disturbanced in the underground after unloading will be in a complex stress states,which will cause compression failure or tension shear failure under the high water pressure,its failure mode by the stress state of the crack was determined based on the principle of rock fracture mechanics,then the cracking characteristics at the crack tip and the fracture mechanics of rock bridge were studied,and the corresponding value of the critical pressure and the splitting tensile strength values of the crack were determined.The damage characteristics of the surrounding fracturing rock in the high water pressure with simulation was studied.The results show that the tunnel surrounding rock driven by the penetration of high water pressure begins to have hydraulic fracturing,and forms a tensile shear splitting area with the development of water leakage.The compression zone outside of the splitting tensile area is immediately formed,and then the tensile shear zones and compression zone continue to expand until the pressure flow attenuation is stable." @default.
