摘　　要： 在霍普金森试验系统上进行了花岗岩破坏的动静组合加载实验,根据实验结果,分析了岩石在动静组合加载下损伤断裂机制与特征.结果表明,不同动静组合加载下岩石破碎的粒度分布具有明显的率变效应;采用张开位移法计算出了岩石破裂时裂纹的宽度. The tests of granite failure under coupled static - dynamic load were made on the SHPB test system. Damage and fracture property of granite under coupled static - dynamic load had been analyzed based on the experi- mental results. The results show that the fractal dimension has significant effect relating to strain rate of samples. The width of crack had been calculated using opening - displacement method.
