The induced stress of initial damage zone results in the redistribution of surrounding rock stress when the micro-crack closes after hydraulic fracture.
水力压裂后，当微裂缝闭合时初始损伤带的诱导应力导致围岩应力重新分布。
The simulation results reflect macroscopic failure evolution process induced by microscopic fracture subjected to hydraulic loading, which agrees well with the experimental results.
数值模拟再现了水压致裂过程中岩石由细观微破裂到宏观破坏的演化过程，并且与试验结果表现出了较好的一致性。
