摘要：

为了将超高韧性水泥基复合材料(UHTCC)应用于大跨径钢箱梁桥，研究双材料界面的力学性能. 采用无切口单边对称加载复合试件，研究UHTCC与钢材界面剪切型裂缝扩展过程. 利用数字图像相关法(DIC)，验证该方法用于定量测定双材料界面剪切型断裂韧度的可行性，探究不同界面处理方式对复合试件界面剪切型断裂韧度的影响. 试验结果表明，采用UHTCC-钢材无切口单边对称加载复合试件，结合DIC技术可以实现界面纯剪切型断裂韧度的定量测试；不同界面处理方式对UHTCC与钢材界面剪切型断裂韧度的影响均较小；UHTCC与钢材界面具有较高的剪切断裂韧度，抗剪切性能良好.

Abstract:

The mechanical properties of bimaterial interface were analyzed in order to apply ultra-high toughness cement-based composites (UHTCC) to long-span steel box girder bridges. The propagation process of shear crack at the interface between UHTCC and steel was analyzed by using non-notched unilateral symmetrical loading composite specimens. The feasibility of the method for quantitative determination of interfacial shear fracture toughness of bimaterials was verified by digital image correlation (DIC) method. The effects of different interfacial treatment methods on the interfacial shear fracture toughness of composite specimens were analyzed. The test results show that the quantitative test of pure shear fracture toughness of interface can be realized by using UHTCC- steel without notch unilateral symmetrical loading composite specimen combined with DIC technology. Different interface treatment methods have little effect on the shear fracture toughness of the interface between UHTCC and steel. The interface between UHTCC and steel has high shear fracture toughness and good shear resistance.
Key words: ultra-high toughness cementitious composites    digital image correlation method    interface    shear fracture toughness
