AbstractCircular samples with borehole are numerically loaded using flow-coupled Rock Failure Process Analysis code (F-RFPA2D) under internal hydraulic pressure rising at a constant rate under zero confining pressure to investigate the hydraulic fracture initiation, propagation and breakdown. Our findings are: heterogeneity of rock has a significant influence on initiation, breakdown pressure and irregular hydraulic fracture trajectory; hydraulic fracture initiation occurs considerably early before breakdown pressure is reached; the random location of the individual inhomogeneities results in an irregular hydraulic fracture trajectory.
使用巖石破裂失穩的滲流應力耦合系統研究帶有圓孔的圓形巖石試件水壓作用下的開裂、擴展和失穩過程。結果表明,巖石的非均質性導致破裂的初始壓力和失穩壓力明顯不同,水壓破裂路徑不規則發展。
