Crack Angle Effect on Creep Fracture,In brittle rock, inclination of microcracks greatly influences its mechanical behavior. Due to the complex distribution of numerous initial microcracks in brittle rocks, effects of microcrack inclination on strength and failure of brittle rock hardly is investigated directly.

Crack Nucleation During Creep Fracture,Some stress drops appear during the process of deformation under triaxial compressive tests in intact brittle rocks in Fig. 6.1, and each stress drop is associated with an individual shear band caused by strain localization from the accumulation and nucleation of distributed microcracks.

Chemical Effect of Water on Creep Fracture,The safety and stability of rock engineering are closely related to water, such as roadways, dams, tunnels, and underground chambers will inevitably be affected by groundwater. The physical, chemical, and mechanical properties will change when the brittle rock encounters water chemicals.

Constant Seepage Pressure Effect on Creep Fracture,High seepage pressure promotes the growth of microcracks in brittle rock, which is of great significance to the micro–macro mechanism of rock. Based on Chap. ., this chapter proposes a micro–macro mechanism model of the progressive and creep failure of brittle rock, considering the crack propagation driven by seepage pressure.

Cyclic Seepage Pressure Effect on Creep Fracture,Deep underground projects often face complex geological environments such as high stress and pore pressure, making the disasters of underground engineering rocks induced by rock instability widespread.

Dynamic Damage Effect on Creep Fracture,After the excavation or operation stage of deep underground engineering caverns, the surrounding rock masses bear constant initial ground stress loads, and rock deformation at this time is creep deformation.
