摘要
对卵石、碎石混凝土试件进行了三点弯曲试验和楔入劈拉试验。计算、比较了卵石、碎石混凝断裂韧度、断裂能 ,发现采用三点弯曲法和楔入劈拉法测定的断裂参数接近。
The specimens of boulder concrete and crushed stone concrete were tested through three-point-bending method and wedge-split-tensile method.the paper calculated and compared the fracture toughness and the fracture energy of boulder concrete and crushed stone concrete.it is found that the parameter of the fracture,tested by three-point-bending method and wedge-split-tensile methodis approaching to each other.
