| 摘 要： | 由楔入劈拉和三点弯曲梁断裂实验模型,测定了带预制裂缝混凝土试件的变形随加载而变化的规律,得到了反映混凝土断裂特性的数据曲线. 采用电测法对楔入劈拉试件的断裂过程进行了测定;用电子散斑干涉法（electric speckle pattern interferometry）测定了三点弯曲梁的裂纹端部的面内位移,为深入研究混凝土断裂特性提供了有效的实验分析方法.

| Abstract: | Both wedge splitting test specimen and threepoint bending beam test specimen are applied to determinate the load and deformationof concrete specimens with prefabricatedcrack.The facture process of wedge splitting specimen is monitored by electromotivemethod.Fracture properties of concrete are represented by the useful data and curves gained from the tests.The electric speckle pattern interferometry(ESPI) is used to measure the in-plane displacement of crack tip field under three-point bending beam and valuable information is obtained.The methods are suitable to research on characteristicsand fracture properties of concrete. |
