摘要
采用反射式动态焦散线法研究水泥石在高速冲击下的动态断裂韧性。针对现有的水泥石材料，分析了不同填料对水泥石断裂韧性的影响，为工程实际应用提供可靠的理论依据。
The dynamic caustic method is a power-ful tool to evaluate the dynamic stress intensity fac-tors. By means of the reflective type of this method,the dynamic fracture toughness about some mix de-signs for concrete under impact loading is deter-mined, and the contrast and influence of dynamicfracture toughness about the different mix designsfor concrete are compared and analyzed.
