abstract: In this study, sprayable strain-hardening fiber-reinforced cementitious composites (FRCC) were applied to strengthen the concrete slabs in a concrete-face rockfill dam (CFRD) for the first time. Experimental, numerical, and analytical investigations were carried out to understand the flexural properties of FRCC-layered concrete slabs. It was found that the FRCC layer improved the flexural performance of concrete slabs significantly. The cracking and ultimate loads of a concrete slab with an 80 mm FRCC layer were 132% and 69% higher than those of the unstrengthened concrete slab, respectively. At the maximum crack width of 0.2 mm, the deflection of the 80-mm FRCC strengthened concrete slab was 144% higher than that of the unstrengthened concrete slab. In addition, a FE model and a simplified analytical method were developed for the design and analysis of FRCC-layered concrete slabs. Finally, the test result of FRCC leaching solution indicated that the quality of the water surrounding FRCC satisfied the standard for drinking water. The findings of this study indicate that the sprayable strain-hardening FRCC has a good potential for strengthening hydraulic structures such as CFRDs.

abstract: 该研究使用双面剪切试验对500 d长龄期的超高韧性水泥基复合材料(UHTCC)、活性粉末混凝土(RPC)和UHTCC/RPC界面的剪切强度进行了测试，并结合数字图像相关技术对其破坏过程进行了观测。结果表明，UHTCC、RPC和UHTCC/RPC界面均表现出良好的剪切延性，在加载过程中均未发生脆性破坏。此外，改进浇筑工艺和提高粘结界面的粗糙度均能够提高UHTCC/RPC界面剪切强度。将现有的界面剪切强度计算经验公式与试验结果对比发现现有的经验公式无法准确预测UHTCC/RPC的界面剪切强度。该研究建立了UHTCC/RPC界面剪切试验的有限元分析模型，并使用COHESIVE单元模拟界面行为，模拟结果与试验结果吻合较好。
