用三点弯曲试件测试了岩石与混凝土界面裂缝的断裂能及断裂韧度,试验结果表明:岩石与混凝土界面裂缝的断裂及断裂韧度均小于混凝土的相应值。
The fracture energy and fracture toughness of rock and concrete interface cracks were tested by three-point bending test. The experimental results show that the fracture and fracture toughness of rock-concrete interface cracks are less than the corresponding values of concrete.
