摘　　要：混凝土材料的非线性单轴动态强度J准则基于理论推导得出,是单参数强度准则,便于应用。本文通过水工大骨料混凝土单轴动态加载试验,基于J准则建立了适用于地震加载速率的三级配混凝土非线性单轴动态强度准则,并对J准则中的材料参数取值进行了分析和比较,得出水工大骨料混凝土单轴受拉加载下的动态强度相对增长率要高于单轴受压加载的结论。The nonlinear uniaxial dynamic strength J-criterion of concrete material is derived based on the theory,which is a single parameter strength criterion.In this paper,through the uniaxial dynamic loading test for hydraulic large aggregate concrete,the nonlinear uniaxial dynamic strength J-criterion for three graded concrete under seismic loading rates is established,and the material parameter in the J-criterion is analyzed and compared.It is concluded that the relative growth rate for large aggregate concrete under uniaxial tensile loading is higher than that of uniaxial compressive loading.
