摘要(Abstract)：

岩石动态断裂韧性是岩石动力学的基本力学参数之一,也是评价岩石抵抗裂纹动态起裂和扩展性能的重要参数之一。随着采矿工程、岩土工程的不断发展,冲击动态载荷下岩石动态断裂韧性的研究也愈来愈为国内外岩土工程界所关注。综述了冲击载荷下岩石材料动态断裂韧性测试研究进展,主要介绍了冲击载荷下岩石动态断裂韧性测试技术研究成就及其优缺点,并就冲击载荷下岩石动态断裂韧性测试研究发展趋势给予展望。
The dynamic fracture toughness of rock is one of the basic mechanical parameters of rock dynamics.It is an important estimating parameter for dynamic crack initiation and expansion properties of resistance rock.With the development of mining engineering and geotechnical engineering,rock dynamic fracture toughness under impact load is more and more concerned in the geotechnical field at home and abroad.The development and new achievements on rock dynamic fracture toughness testing under impact load was summarized,the testing technology research achievements and their advantages and disadvantages of rock dynamic fracture toughness under impact load and the trend of development of rock dynamic fracture toughness under impact load were introduced.
